Dense Refractory Brick Fused Zirconia Mullite Fire Firebricks in Good Price
Product Introduction:
Zirconia mullite brick is made of high -class zircon sand and alumina powder as raw material.After mixing,shaping,drying,sintering at high temperature shuttle kiln the zircon-mullite brick has such advantages as high bulk density, high strength, good thermal shock resistance, high temperature erosion resistance and good slag resistance.
Application:
It is mainly used in tank bottom,tank superstructure,perfume-bottle feeder,covers for working tanks and soda lime glass.
Features:
1.High density.
2.Good slag resistance.
