A hollow glass microspheres made up of some minor ceramic elements with the smooth silica-aluminum is Cenosphere. Its derivation has been done from the extreme fire of coal-fired power plants and now it is being used to improvise the qualities of manufactured products in India.
In India, Cenospheres are made of iron, alumina & silica by Petra Buildcare Products. In thermal power plants, burning coal produces fly ash which has ceramic particles largely made of alumina and silica.
The size range of cenospheres varies from 1 to 500 microns with 3000+ psi average compressive strength. In low-density concrete, Cenosphere can be used as fillers; It can also be used in plastics and composite materials such as kayaks, surfboards, bowling balls and for automotive components it can be used in floor tiles, fire bricks, and other industrial materials.
Cenospheres are hollow glass microspheres that are a by-product of coal burning power plants. When pulverized coal is burned at power plants fly ash is produced. Cenospheres are the lighter particles that are contained within the fly ash.
Most cenospheres are "harvested" or scooped up from ash ponds. Ash ponds are the final resting place for fly ash when wet disposal is carried out. Some cenospheres are also collected at the power plants themselves. The wet hollow glass microspheres are than dried, processed to specifications, and packaged to meet customer requirements.
Not all cenospheres are alike. In fact, they can be quite different. The properties of cenospheres depend on the consistency of the coal used and the operating parameters of the power plant. As long as these two factors remain constant, the cenospheres will be quite consistent.
