　　七、Zircon brick

Zircon refractory products are acidic material is a natural zircon sand as raw material products. Zirconium refractory slag resistance good, small coefficient of thermal expansion, thermal conductivity decreases with increasing temperature, high load softening temperature, strong abrasion resistance, thermal shock resistance, which has become in various industrial fields important material.

　　八、Low-porosity clay brick for glass furnace

This product uses special shock refractory castable molding process to produce glass with a low porosity clay brick kiln, and the appearance of its physical and chemical indicators are better than national standards. Anti-corrosive liquid glass of the product is superior to conventional slip cast molding process and ramming molding process products, especially for use in masonry glass kiln bottom, middle and lower thermal storage wall, the lower checker bricks, arch support and other parts.
