1. High refractoriness:
Cenosphere have extremely high refractoriness, generally reaching 1600-1700 degrees Celsius, making them an excellent high-performance refractory material.
2. Lightweight, thermal insulation:
Cenosphere is not only light in weight (bulk density 250-450 kg/m3), but also excellent in thermal insulation (thermal conductivity at room temperature 0.05-0.1).
3. High hardness and high strength:
Because Cenosphere is a hard glass body formed from the silicon-aluminum oxide mineral phase (quartz and mullite), the hardness can reach Mohs 6-7, the static pressure strength is as high as 70-140MPa, and the true density is 2.10-2.20 g/cm3. Therefore, Cenosphere has high strength.
4. Fine particle size and large specific surface area:
The natural particle size of Cenosphere is 1-250 microns. The specific surface area is 300-360g/cm2, which is similar to cement.
Therefore, Cenosphere does not need to be ground and can be used directly.
5. Excellent electrical insulation:
Cenosphere is an excellent insulating material and does not conduct electricity.
