Application


Ceramic foundry sand is a green casting sand. Because of its high refractoriness, it can be used in lost foam casting and investment casting which can promote the quality of castings, decrease the cost and make a good environment. As a kind of green sand in casting, it can also be used in moulding making, metal casting, foundry molding.

It has the advantages of high temperature resistance, no crushing, no dust, spherical shape, high air permeability, good filling, and no harm of silica dust.

Ceramsite used for casting is accepted by more and more people, and this material is also more and more popular in refractory and casting.
