Applications for Cenospheres and Related Benefits

Cenospheres are inert, hollow spheres consisting mostly of silica and alumina, filled with gas as carbon dioxide and/or nitrogen. Cenospheres are a by-product of coal combustion with thermal power plants.

Main benefits:

• weight reduction
• thermal conductivity decrease
• fluidity boost
• temperature resistance > 1450 °C
• insulation

Typical applications:

• ceramic, refractory and foundry products
• construction
• insulation materials
• sandwich and fireboard wall panels
• polymers and plastics
• well-field cementing solutions
