Description：
Ceramic sand is a kind of fused ceramic sand,it is made from calcined bauxite with main content aluminium oxide processed by melting,blowing,sieving and blending.
Characters:
1.Low thermal expansion coefficient
1.spherical shape,good flow ability,easy to shakeout
2.smooth surface,compact structure
3.chemically neutral material
4.high temperature resistance,good refractoriness
5.Recycle up to 10 times,highly cost effective.
6.Save resin consumption with casting tech such as shell molding,Resin coated sand casting,Vacuum casting,etc.
