Top Reasons Behind the Increase in Export of Cenosphere from India?

A cenosphere is a lightweight, inert, hollow sphere which is made largely of silica and alumina filled with air and inert gas. Typically, cenosphere India is produced as a byproduct of coal combustion at thermal power plants. Usually, the color of this byproduct varies from gray to almost white, having a density of about 0.4 to 0.8 g/cm3 which gives them a great buoyancy. Combustion is a high-temperature exothermic redox chemical reaction of a fuel and an oxidant, generally, atmospheric oxygen producing oxidized in a mixture of a chemical reaction is termed as smoke. Burning in a fire producing flame, the heat produced can make combustion self-sustaining. This often goes through a complicated sequence of elementary radical reactions. That is solid fuels including wood primarily undergo endothermic pyrolysis to produce gaseous fuels where combustion is supplied to produce more heat.


The particles of Cenosphere India are hard, rigid, innoxious, lightweight, waterproof, and insulative making them highly useful for a range of products, notably as fillers. Filler particles are mixed with materials such as composite material, plastics, and concrete to lower the consumption and improve some properties of the mixture. Globally more than 555 million tons of fillers are used annually for different applications including paper, paint and coatings, plastics, rubbers, concrete, adhesives, and sealants.  Cenospheres are also used widely as fillers in cement for producing low-density concrete. In recent years, manufacturers also started using cenospheres for filling metals and polymers to make them lightweight composite materials with enhanced strength than other types of foam materials. These composite materials are known as syntactic foam. Aluminum-based syntactic foams are widely used in the automotive sectors.

The combustion at thermal power plant takes place at the temperature of 1500o to 1750o C (2730o to 3180o F) through complicated physical and chemical transformation. However, the chemical composition and structure of Cenosphere India considerably depends on the composition of coal then generated. Basically, the ceramic particles produced in fly ash have three type of structure:

  • Precipitator (solid)
  • Cenospheres (hollow)
  • Plerospheres (hollow with large diameter)

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
