High Pure Fused Mullite,refractory mullite
High pure fused mullite is a kind of superior refractoy raw material,it has the advantage of homogeneour expansion,excellen thermal shock resistance,high refractoriness under load,low creep under high temperauter,strong hardness,chemistry corrosion resistance,good wearing proof and so on.
Mullite is widely used to blast furnace low creep sillimanite brick,mullite brick for alkali-free glass settling pond,seggar&pushed slab for high temperautre tunnel kiln,etc..
