cenospheres/microsphere

Cenospheres arise as light weight filler from a washing process of fly ash from coal fired power plants.
The grain size of cenospheres varies from 0 – 700 µm. Specific grades, f.e. 0 – 100 µm or 100 - 700 µm, can be produced by sieving. It could be used on Cement, Construction Materials and Civil Construction Industry
Foundry Industry
Oil and Gas Industry
Performance Fillers for Plastics, Paper, Paint and Coating
Refractory Industry ect
