Ceramic foundry sand

Ceramic foundry sand 1,replacement of Quartz Sands and Silica Sands 2,Low thermal expansion rate 3,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.
