Product Number:
To further improve mullite's corrosion resistance, thermal shock resistance and lower its linear expansion coefficient, SHUO CHENG optimally adds some ZrO2 into Al2O3 and ZrO2 to improve mullite's structure. The fused zirconia mullite possesses excellent heat-conducting property, low expansion coefficient, strong slag resistance and so on, mainly applicable for sliding plate, metering nozzle and long nozzle for continuous casting, key parts of glass kiln, etc.
