Introduction Mullite ceramic plate
Mullite plate or mullite ceramic plate belongs to mullite ceramic. The refractory product 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. Mullite ceramic is with features of high refractoriness under load, compact structure, low porosity and high resistance to corrosion.
