Zircon corundum brick is 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.
1. High bulk density.
2. High mechanical strength at normal and high temperature.
3. Good thermal shock resistance.
4. Low creep and low permanent liner change rate.
5. High performance of chemical stability and alkaline medium erosion.
Primarily used for the erosion parts of the furnace of glass furnace, glass fiber furnace, garbage incinerator furnace, electro thermal furnace, etc
