Refractory raw material,Fused zirconium mullite
Fused zirconium mullite is has the characteristics of good thermal conductivity,low coefficient of thermal expansion and good slag resistance.It can improve the thermal shock resistance and erosion resistance of refractory products which made of fused zirconium mullite,also can enhance the wearing proof property.
Fused zirconium mullite is a kind of ideal raw material,which is widely used to manufacture ladle shrouds,slide gate nozzle,and can be used for glass kiln and refractory castables.
