Cenospheres are inert, hollow spheres consisting of silica and alumina, filled with gas (mostly carbon dioxide and/or nitrogen). It is a by-product of coal combustion with thermal power plants. Cenospheres reduce product weight, assure low thermal conductivity, boost fluidity and increase temperature resistance (> 1000°C).
Typical applications are wellfield cementing, construction, isolating compounds, sandwich and fireboard wall panels, polymers and plastics.
