Cenosphere Exporter Delivering Quality Fly-ash

Cenosphere is a type of sialic bead and minute glass particle that is extracted from fly ash in thermal power plants, for the reason that it can float on the water. Its chemical composition is SiO and AlO. They also recognized as Hollow Ceramic Microsphere and Cenosphere exporter calls it with trade names like Spherelite, Cenolite, and Lifefilletc Standard Grades. In the present situation, we grasp the cenosphere disc that is blended with fly ash-talc with absorbent material (Naphthalene) and 10 % Sodium Hexa Meta phosphate (SHMP) supplement to the mixture. As upsurge in the talc percentage, the concentration of water is decreased while the absorbent material (Naphthalene) is added up to 60% the absorption of water slowly starts increasing. Roughly 75% of India’s electrical energy is made by burning coal in thermal power plants, though hydroelectric production covers around 20%, whereas the remaining 5% is produced mainly by solar, nuclear, and wind power coal burning leading to the generation of huge amount of solid waste in the form of fly ash.


Cenosphere is extensively used as a lightening mixture for oil-well cement as

  • it can increase the liquidity of cement slurry,
  • it delays weightlessness time of cement slurry,
  • mend the anti-gas channeling ability of cement slurry,
  • reinforce the strength of the cement slurry,
  • it can react with the cement hydration materials and generate compounds that have gelation property, conductivity quantity and sponginess of cement stone.

Their chemical characteristics, sphere-shaped and hollow morphology, as well as their mechanical and energy lightening properties, that can be abused to the main advantage obtained by cenosphere in contrast with other alternative filling compounds is their low density. Low thermal shock and low impression strength caused by Silica is the main component of fly ash. Cenosphere exporter uses a 600 kg bags with polyethylene liners that are required to be stored in a dehydrated area far from every source of water. They are dedicated to providing Cenosphere that is highly efficient, consists high quality, and have high environmental production material for the global customers.

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

  • 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.

What is the type cenosphere exporter use to export?

 Fly Ash: It is one of the residues generated in the combustion of coal. Fly ash is generally taken from the chimneys of power generation, where the bottom ash is removed from the foot of the furnace. Before, fly ash was usually released into the atmosphere with the smoke stack, but today pollution control equipment has mandated to capture the ashes earlier to release. Conditional upon the source and character of the coal being burned, the mechanisms of the fly ash produced vary significantly, but all fly ash includes generous amounts of silica (silicon dioxide, SiO2) (both amorphous and crystalline) and lime (calcium oxide, CaO).

ASTM 618F: Fly ash is defined into two classes by ASTM C618- Class F fly ash, and Class C fly ash. Both the classes differentiate each other on the basis of the amount of silica, calcium, iron, and alumina present in the ash. Thus, the chemical properties of the fly ash are generally influenced by the chemical contamination in the coal burned.

The burning of harder, older anthracite and bituminous coal typically produces Class F fly ash, whereas Class C fly ash is produced from the burning of younger lignite or sub bituminous coal, in addition to having pozzolanic properties, also has some self-cementing properties.

Quality Approved Cenosphere from India

Like fly ash, cenospheres are naturally occurring by-products of the burning process at coal-fired power plants. Unlike fly ash though, cenospheres are lightweight, inert, hollow spheres comprised largely of silica and alumina and filled with air and/or gases. Since they are inert, they are not considered a pozzolan. And because they are very small and have high compressive strengths, cenospheres can be used as structural lightweight filler.

How cenosphere from India are produced?

Cenospheres are produced in very large amount in thermal power plants. They are always looked upon as fillers used to reduce the density and cost of the polymer. If cenosphere particles are allowed to remain properly dispersed by taking it in lower concentration, significant improvement in its mechanical, thermal, electrical, crystallinity, colorimetric and morphological properties are expected. To make it happen, epoxy/cenosphere composites were prepared, having lower concentration of cenosphere. Concentration of cenosphere in epoxy, cured with triethylenetetramine, was changed as 0, 3, 5, 7 and 10. Tensile Strength, Tensile Modulus, Percentage Elongation at Break and Crystallinity decreased, whereas, Flexural Strength and Flexural Modulus were found to have increased by 50% and above 100% respectively at 7 phr loading of cenosphere in epoxy. Thermal and electrical stability also increased with increase in concentration of cenosphere in the epoxy; however, the samples became blackish with increased addition of cenosphere. Using SEM analysis it was found that, cenospheres were properly and uniformly dispersed at 7 phr concentration and formed aggregates at 10 phr concentration.
