Cenosphere, sometimes called microsphere, is a light weight, inert, hollow sphere made largely of silica and alumina and filled with air or inert gas., typically produced as a byproduct of coal combustion at thermal power plants. The color varies from gray to almost white and their density is about 0.6–0.9 g/cm³, all these property give it a widely application for insulation,refractory,oil drilling,coating,construction use.
