What are Cenospheres?

Cenosphere is used widely for various Industrial applications due to its excellent composition properties. Cenospheres are the by-product of coal combustion at the thermal power plant. They are lightweight, inert, and hollow spheres that are largely made up of alumina and silicate. The colors of the Cenosphere vary from gray to white depending on the type of coal used for the combustion process. They have a density of about 0.4–0.8 g/cm3 (0.014–0.029 lb/cu and are filled with inert gases which gives them great buoyancy.

The properties of Cenospheres allow them to be used for various Industrial purposes. The tiny ball of fly ash is useful because of its mechanical strength, small size, low density, high melting temperature, and thermal insulating properties. In particular, Cenosphere is ideal for providing thermal insulation to coatings or paints and imparting properties of resistance to corrosion. Cenospheres are multifunctional in nature and can be used as binders for thermosetting and thermoplastics. Here are the uses of Cenospheres in various Industries.
