Product Description
Cenosphere(floating bead) is a kind of fly ash hollow which can float on the water surface. It is gray white, thin, and hollow with light weight.The chemical composition of the cenosphere is mainly silica and aluminum oxide.
It has the characteristics such as fine particle, hollow, light weight, high strength, wear resistance, high temperature resistance, insulation, and flame retardant. It is a good temperature keeping refractory materials.
