Good Thermal Shock Resistance Zircon Mullite Brick, Refractory Brick Cheap
Introduction
Zircon mullite brick adopts mullite as aggregates, sintered zircon as raw materials, after mixing, shaping, drying, sintering at high temperature in shuttle kiln, the whole process is finished.
Features of zircon brick:
- Good thermal shock resistance.
- Low creep and low permanent liner change rate.
- High performance of chemical stability and alkaline medium erosion resistance.
