Advantages and use cases of cenospheres

Größenvergleich MikrosphärenCenospheres 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.

Their main advantages:

  • product weight reduction
  • lowering the thermal conductivity
  • fluidity boost
  • increasement of temperature resistance (> 1000 °C)

Typical applications:

  • construction
  • isolating compounds
  • sandwich and fireboard wall panels
  • polymers and plastics.

We are looking forward to your requests about our cenospheres.
