  • Lightweight aggregate –Considering the lightweight aggregate, cenospheres can be used for replacing some normal-weight sand particles because they have a density of 0.7 which is lower than water, i.e., 1.0, whereas quartz sand particles have a density of 2.65 on an approx. Moreover, there is a prime advantage of cenosphere particles over the other lightweight aggregates and it is that they are generally invisible when mixed in the concrete even if it is refined.
  • Workability enhancer – As a matter of fact, cenosphere particles comparatively have small spherical particles and thus, they are treated as microscopic ball demeanors when mixed in a concrete. Blending the cenosphere particles with the normal weight concrete mix will result in the improved workability because of the ball bearing effect.
  • Bulk filler – Since the Cenosphere Suppliers India deliver extremely fine coal fly ash particles, they are ideal for use in cement grout slurry as cenosphere increases the volume of grout without the need of adding more cement to the mixture and also the aggregate gradation reduces shrinkage.

Demand of Cenosphere exporter in Various Industries

A cenosphere is an inert, lightweight, and hollow sphere that is largely made up of silica and alumina filled with air and inert gas, which is usually produced at thermal power plants as a byproduct of coal combustion. Generally, the color of the cenosphere ranges from gray to almost white with a density of about 0.4-0.8 g/cm3 (0.014-0.029 lb/cu in) which contributes as a great buoyancy. As a result, cenosphere is exclusively considered as a free flowing powder that is comprised of hard-shelled, tiny, and hollow spheres collected from coal ash. Because of these qualities, the demand for the cenosphere exporter has immensely increased as the byproduct consist of higher particle strength, lower value of thermal conductivity, ultra-low density, and impermeability that is suitable for its usage in various industries. The particles are 75% lighter compared to other different minerals which are used as fillers in clay, talc, and calcium carbonate and 30%, furthermore, lighter than general pitches.

Rising Demand of Cenosphere Suppliers India

Cenospheres are hollow, low-density, spherical, and free-flowing aluminosilicate microspheres that are produced as a by-product of coal ignition at the coal-fired power plants. It is a rich-in-ceramic industrial waste formed at the time of coal combustion in the thermal power plants. Inside the each sphere there is a near vacuum that produces good properties of thermal and acoustic insulation making a product ideal for automotive acoustic insulation applications where the mass is a major factor to be considered. These spheres are used globally in several automotive application including tyres, brake linings, friction linings, dashboard, and clutch facings. The broad range of usage has increased the demand of cenosphere suppliers India in the industry.


According to the global market report, cenospheres are providing emerging opportunities along with the future effects of major drivers and challenges that support the managers to make cost-effective decisions in favor of the business. The market report measures the major opportunities for the cenosphere suppliers India in the marker and underlines the factors that are responsible for the growth of the industry. The increasing demand from end-use industries including refractory, construction, paints and coatings, and oil and gas, which is expected to take the market to the next level in the near future.  However, restricted sources of raw material and deficiency of quality control across developing countries are key factors that may restrain the growth of the industry.

The Gray Cenospheres segment is estimated to experience the highest growth in the upcoming years because of its wide uses across the industrial segment. The demand will increase also because the gray cenosphere is produced more frequently as compared to the white cenosphere in fly ash. The demand for gray cenosphere suppliers India is rising because they deliver quality material which contains a low content of alumina and is high in silica and iron content that is used in a number of applications such as plastics, concretes, coatings, resins, bricks, and rubbers

Cenosphere from India Has Various Usages

Cenospheres are sometimes also called as microspheres that are widely used in a variety of materials from plastics and caulking to paints and finishes. Although, they are sometimes also used in concrete. Cenosphere from India consists a range of uses in concrete countertops including:


  • A lightweight aggregate – cenospheres can be treated as a substitute of the normal-weight sand that is used in concrete. They have a density that is less than water (approx. 0.7 vs water’s 1.0); quartz sand particles typically have a density of about 2.65 which means that 1 pound of cenospheres takes up the similar absolute volume as about 3.8 lbs of sand.
  • A workability enhancer and extra-fine aggregate – Cenospheres are known for their very small spherical particles. As such they act just like minute ball bearings in a concrete mix. By adding cenospheres to a conventional weight concrete mix will increase workability because of its ball bearing effect and since they are also structural aggregate, they expand concrete density and strengthen it by providing a better packing. Furthermore, the added fines mend the trowelability and finishability. Usually dosages of 1% to 5% by weight of aggregate are added to a concrete mix to improve the workability.
  • A bulk filler and shrinkage reducer in cement grouts – Meanwhile Cenosphere from India have very fine particles and are generally light in color; they are perfect for the use in cement grout slurry. By adding the bulk from the cenospheres, it not only increases the volume of grout without adding more cement, but also the fine aggregate gradation of the particles supports to reduce the shrinkage. In spite of everything, cement grout is still a kind of concrete, so the same rules apply.  Finally, the spherical shape marks packing pinholes at ease and more effective because of the polishing action delivered by the particles. And the spherical shapes are further likely to “roll” into small holes better than pointed or angular crushed particles. Typical cenosphere measured quantity is approximately around 10% to 30% by weight of cement.

A Brief about Cenospheres

Coal fly ash is a compound blend of anthropogenic materials formed during the combustion of pulverized coal in coal-fired power plants. They carry environmental concerns that lead to air and water pollution. The efforts have been done for reducing the production of coal fly. Cenospheres are light, low density, thin-walled hollow ceramic microsphere with distinctive properties. Conventional cenosphere production procedures involve the separation of cenospheres from coal fly ash. Fine fractions of non-magnetic cenospheres comprise 2.6–3.5 wt % Fe2O3 and embrace globules with an even smooth surface and shells with different degrees of absorbency. The aluminum absorption rise leads to an increase in the mullite phase content and a decrease in the average sphere diameter, shell thickness and porosity, glass-crystalline, and the crystalline quartz content.


The advantages of Cenospheres:

  • Lightweight
  • Spherical shape
  • Inert
  • Free flowing
  • High-melting point
  • Insulating
  • Electrical properties
  • Low oil absorption
  • Good packaging factors
  • Versatile filler with applications in an extensive range of products for both commercial and industrial use.

However, in each case, Fillite is used for its unique properties, such as strength, low density, and chemical resistance. Fillite can be used for the applications in Cement, Latex emulsions, Polyurethane, PVC, Epoxy Resins, and Unsaturated Polyester Resins.

Properties of Cenospheres:

  • Cenospheres are made up of silica, iron, and alumina.
  • They have a size ranging from 1 to 500 microns with a usual compressive strength of 3000+ psi.
  • Colors range from white to dark gray.
  • They are chemically inert & are reclaimable and labeled as environmentally sound.
  • They are formed during the molten state of ash and attain spherical shape to have minimum surface tension.

The residue from coal after combustion has been a challenge for Indian power sector, which is dominated by coal. Presently the country produces approximately 160 million tons of fly ash, of which merely 80 million tones is being utilized. Improvements in the durability and strength of manufacturers’ end products and a reduction in product weight enhance marketing strategies are required.  Manufacturers are dedicated in producing quality chemical and physical product on a consistent basis is critical for the end use customer.

Properties and Components of Cenospheres

A cenosphere is a lightweight, hollow sphere made largely of silica and alumina and filled with air, metals, or gas. The Cenospheres are manufactured as a byproduct of coal combustion at thermal power plants. Cenosphere-based compounds were fabricated and categorized for their structural and mechanical properties such as tensile, flexural, impact and vibrant mechanical properties such as storage and loss moduli as a function of temperature. The structural qualities were characterized by Scanning Electron Microscopy (SEM) and Wide-Angle X-ray Diffraction (WAXD) though the thermal characterizations were prepared by conducting Differential Scanning Calorimetric (DSC) and Thermo-Gravimetric Analysis (TGA). The DSC studies revealed that increase in cenosphere content has resulted in a decrease in crystallinity of the composites.


The amount of separation in retrieving the Cenospheres from coal fly ash has been valued for both wet and dry separation processes through applying the terminal velocity concept of particles. The diameter and density of the particle are determined by sieving industrial cenospheres and coal fly as type IV. Depending on the estimation, the dry separation process executed similarly to the wet separation process, with a most favorable Newton’s efficiency of 0.54, just slightly lower than that of the wet separation process of 0.6.

The mortar cubes can be made with a combination of Cenospheres and silica fume as a standby for the cement. The test on mortar cubes shown that cement loses its strength because of the replacement of cenosphere, but the loss can be calm down by adding silica fume to it. The strength decrement decreases by ages, displaying that the strength attainment is reduced by the addition of cenosphere. The microstructure has also been studied to show the disintegrated structure on advanced replacement of cenosphere. It was also noted that the hydration products react with cenospheres and, due to this; decline in the quantity of portlandite was witnessed resulting in strength decrement.

Need of Cenosphere Exporter for a Variety of Products

A cenosphere is a lightweight, inactive, hollow sphere occupied by inert air or gas, usually produced as a byproduct of coal combustion at thermal power plants. They are hollow microscopic balls which are made from smooth silica-aluminum and other minor elements of ceramic. Cenosphere exporter exports the cenosphere which is hard and rigid, in noxious, light-weighted, and insulative. Such qualities make them useful for a variety of products. They can be used as fillers in cement producing a low-density concrete. A quality cenosphere is produced from the burning coal in thermal power plant producing fly ashes which contain ceramic particles.


A variety of products where Cenospheres can be used:

Syntactic foam – cenosphere have been used as filler for syntactic foam providing lower cost, high-level of strength, sound proof, buoyancy and several thermal protections. A ‘syntactic’ is an ordered structure portion of the hollow space, whereas the ‘foam’ relates to the cellular nature of the cenosphere.

Petroleum drilling – the petroleum has been contacting the cenosphere exporter for so many years for reducing the density of a petroleum cement paste without even adding the water content.

Plastics and Polymers – the re-formable shape and strength of cenosphere forced manufacturers of plastics and polymers to use the fly ashes of the cenosphere to avoid shrinking of thermoplastics and thermosetting plastics.

Concrete – cenospheres has been using for concrete since so many years as it provides extra strength whilst lowering the density as they are capable of replacing some of the weight of the sand used in concrete. Cenosphere consists of density which is lower than the water, averaging cenosphere’s 0.7 vs. water’s 1.0, whereas the density of sand particles is about 2.65. Which means 1 pound of cenosphere takes up the same volume as about 3.8 lbs. of sand.

Pharmaceuticals – Cenosphere is occupied with inert air and gasses. Cenosphere exporter creates small balls from the cenospheres which are used for perfect transport device when coated with the drugs. Cenospheres when covered with silver oxide then can be integrated for dressing purposes in order to faster wound healing.

Some Basic General Information about the Cenosphere from India

Cenospheres are light weight, inert hollow sphere comprising largely of silica & alumina and filled with air or inert gas. Cenosphere from India is naturally produced by the burning process of crushed coal-fired boilers. They are molded during the molten state of ash and reach spherical shape to have minimum surface. Inert gasses flowing along the burning gas stream also get locked inside the spheres. The bubbles caused by the inert gas combustion get into multiple forms with the frozen particles or in a concentric form, whose diameter is near the diameter of the particles.


The bubbles are found moving on the surface of fly ash. Cenosphere from India is unique free flowing powders composed of hollow, hard-shelled, and minute spheres. Cenospheres are formed from a small portion of the Pulverized Fuel Ash (PFA) which is produced from the burning of the coal in power stations. These are made up of iron, silica, and alumina. Generally, the size of the cenosphere particles ranges from 1 to 500 microns with an average compressive strength of above 3000 psi having a color variation from white to dark gray.

The factors included in the property of cenosphere are:

  • Spherical shape
  • Inert
  • Lightweight
  • Free flowing
  • Insulating
  • Hard electrical properties
  • High melting point
  • Low oil absorption
  • Good packing application
  • Versatile filler

These can be used for both commercial and industrial purposes for oil well cementing and PVC cushion vinyl flooring. However, Fillites are also used due to its unique property of chemical resistance, low density, and strengthening capacity. Fillites are used for the following applications:

  • Polyurethane,
  • Cement,
  • Latex Emulsions,
  • PVC,
  • Epoxy Resins; and
  • Unsaturated Polyester Resins.

Most of the Cenosphere from India are restored from the ash ponds at the coal fire plants. It is a huge challenge for the Indian power sector to generate fly ash from the combustion of the coal, as the sector is dominated by coal. Today, around 53% of the total power capacity is based on the coal. Today, the country generates 160 million tons of fly ash, out of which only 80 million tons are being used.
