Ceramic crucible chooses melted quartz as raw material, is mainly applied in the smelting of platinum, gold, stainless steel and other alloys. It has high purity, good corrosion resistance, low thermal conductivity, small expansion coefficient, good high temperature resistance and thermal stability. Its main component SiO2 >98%, impurity(K2O,Na2O,Fe2O3)<0.2%. It has high strength, high thermal shock resistance, and can resist the pressure under normal temperature>70MPa .
