Product Description

Cenosphere is a lightweight, inert, hollow sphere made largely of silica and alumina and is filled with air or inert gas. It is typically produced as a byproduct of coal combustion at thermal power plants. The color of cenospheres varies from gray to almost white and the density is about 0.*0.8 g/cm3. Cenospheres are small, high strength, extremely lightweight, free flowing, non porous, hollow ceramic spheres. 

The hollow ceramic glass bubble shape of the Microsphere results in a variety of uses other than simply being used as a light-weight filler. Cenospheres are used as a Filler to replace minerals and resins where the benefits may be as diverse as weight reduction, improved thermal insulation, reduced shrinkage, improved fire resistance or simply easier application.
