Mullite stone fight to peel off brick

Mullite refractory brick has high refractoriness under load, compact structure, low porosity and high resistance to corrosion.

Mullite refractory brick is composed of high quality mullite and high purity fused corundum as raw materials with addition of specified binder by shaping at high pressure and sintering at high temperature. With features of high refractoriness under load, compact structure, low porosity and high resistance to corrosion.
