A brief About the Particles by the Cenosphere Suppliers India

A Cenosphere is an inert, lightweight, hollow sphere consists largely of silica and alumina and the particles are filled with air or inert gas, typically formed as a byproduct of coal combustion at thermal power plants. However, the 28 years ago the definition was different. Until the 1990s it was restricted to a largely carbonaceous sphere produced by the oxygen-deficient combustion of a liquid fuel drop cooled below the temperature of 200o C (392o F) before it was actually utilized. The fuel cenosphere specified a combustion source by using fuel injected droplets or the open burning of heavy liquids like asphalt or thermoplastic material that used to bubble when burned; this burning of the bubbles produces airborne droplets of fuel. Thus, the fuel cenospheres are sometimes also used as the synonyms with glass microspheres or microballoons. However, in the present days, the Cenosphere Suppliers India hoard the particles with the density ranging from 0.4 to 0.8 g/cm3 (0.014-0.029 lb./cu in) that gives them a great buoyancy. The color of cenospheres ranges from gray to almost white.


Glass microspheres are tiny spheres of glass manufactured for a broad range of uses including in research, consumer goods, medicine, and several other areas. The spherical size of glass microspheres has a diameter that usually ranges between 1 to 1000 micrometers.

Cenospheres are naturally occurring by-products produced during the burning process at coal-fired power plants. As mentioned above that they are inert, lightweight, and hollow granules comprised largely of silica and alumina, the cenosphere suppliers India don’t consider the particles as a pozzolan. Pozzolans are silicate-based material that reacts with the calcium hydroxide produced by hydrating cement to develop extra cementitious materials. Calcium hydroxide accounts for up to 25% of the hydrated cement which doesn’t contribute to the concrete’s durability and strength. Thus, the pozzolans are mixed with calcium hydroxide to form extra calcium silicate hydrate; the mixture is responsible for holding concrete strength. By consuming in excess:

  • The strength of concrete is improved
  • The density is lowered
  • Efflorescence is decreased

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. The great finished outcome of cenosphere is immeasurable like tiles of space boats, flying machine coatings and oil well bonds.


However, several techniques have been evolved over the last 50 years to mend the metal values from the coal ash. Different studies have focused on the extraction of alumina, carbon, magnetite, cenosphere, and several other metal values. The elements present in coal ash, aluminum, and iron have been tested by the cenosphere exporter to ensure the quality of the particles. Regaining of element components from coal ash has been proficient for its use in the both physical and chemical processes.

For recovering the major constituents of coal ash, a chemical processed test is been formulated and scaled-up in four general categories, that is:

  1. Hydrothermal leaching
  2. Sinter-leach
  3. Gas solid reaction
  4. Direct reduction

Therefore, the cenosphere exporter exports the fly ash particles to multiple industries for various purposes:

  • Foam insulation
  • Coal ash mineral wool
  • Fly ash fire bricks
  • Decorative glass
  • Filler application
  • Light weight refractories
  • Fire abatement application

Cenosphere suppliers India Utilizes the Benefits of Hollow Particles

A cenosphere has the physical properties of a lightweight, inert, and hollow sphere that is comprised largely of silica and alumina which is filled with air and gasses. Cenospheres occur naturally as a by-product of the burning process at coal-fired power plants and they comprise the similar properties as of manufactured hollow-sphered products. Cenosphere suppliers India delivers the product for using it in multiple ranges of materials from finished plastics to paints, concrete, and waterproofing. Cenospheres have a range of uses in concrete countertops including a lightweight aggregate, bulk filler and shrinkage reducer in cement grouts, and a workability enhancer and extra-fine aggregate.

Thus, the spherical shape of cenosphere enhances the flowability of most applications providing an even distribution of the filler material. Cenosphere can be used in either dry or wet slurry form due to the natural properties that it consists of. Because of their inert properties, they stay unaffected by water, solvents, acids, or alkalis. Most cenosphere suppliers India prefer to supply the hollow particles as they 75% lighter comparatively to any other minerals that are used as filler and 30% lighter than most resins.


Cenospheres are lightweight, waterproof, insulative, innoxious, solid and intransigent making them intensely valuable in a mixture of items and excellently as the fillers. At the present times, cenospheres are used as the fillers to create concrete with low thickness. However, some of the manufacturers have started using metals and polymers combined with the cenosphere as a filler to produce lightweight composite materials along with the high quality compared to other sorts of froth materials. Though the common properties of cenosphere can be sometimes difficult to handle giving a low-surface territory to volume proportions and because of their inactive properties they remain unaffected by water, acids, solvents, or antacids. There are some benefits of these hollow particles due to which the demand for cenosphere suppliers India is increasing:

  • Reduced crude material costs
  • Reduced pitch demand
  • Improved flowability
  • Improved insulation values
  • Reduced weight of the finished material
  • Resistant to absorption
