Cenosphere Advantage:
1) Excellent fluidity
In hollow micro-spherical shape and with size from 20 to 500micron,cenospheres can improve Fluidity of filler and make it easier to be used .
2) Heat-insulating and sound-insulating
Lower conductivity makes it widely used in producing heat-insulation and sound-insulation materials and Equipments.
3) Chemical stability
Chemical features (alumina silicate) of cenospheres can maintain their integrity while they are utilized in Water,organic chemicals acid,alkali and other solvents.
4) High refractoriness
Cenospheres have a high refractoriness. It can still keep a good stability while being heated over 1000C.
