Cenosphere - Wikipedia

OverviewEtymologyProductionFuel or oil cenospheresThe word cenosphere is a combination of two Greek words:kenos and sphaira which describes the major characteristic of this material. A cenosphere is a lightweight, 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 of cenospheres varies from gray to almost white and their density is about 0.4–0.8 g/cm3, which gives them a great buoyancy. Cf. glass microspheres.
