Ceramic Sand Replacing Foundry Chromite Sand

Ceramic sand called ceramic foundry sand,foundry sand, China Cerabeads,ceramsite 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.
