Ceramic Foundry sands

Ceramic foundry sand1,replacement of Quartz Sands and Silica Sands2,Low thermal expansion rate3,high refractoriness Ceramic foundry sand ,called ceramisite sand,china cerabeads and cerasand too, is made from high quality bauxite, by re-fused and blown to ball type.

With advantage of fine surface smooth finish and air permeability, it is a new type casting material for precision casting, coated sand and self hardening sand etc.
