Product Description Product Description At present, there are two classifications of quartz ceramics. One is crystalline quartz smelted at a high temperature of 1600 ° C, commonly known as quartz sand, crystal. The other is also produced at high temperature. At a temperature of 1200 ° C, the quartz glass is pulverized to produce a substance called quartz glass ceramics. Product Features 1. High temperature resistance. 2. Quartz ceramics not only have the advantages of quartz glass, such as small expansion coefficient, good thermal stability, corrosion resistance, etc. 3. And the manufacturing cost of quartz ceramics is much lower than that of quartz glass, even 10-100 times lower than that of quartz glass.99 Alumina Square Crucible Product propertiesItemSquare Alumina Crucible Chemical CompositionAI2O3≥99 R2O≤0.2 Fe2O3≤0.1 SiO2≤0.2Volume Desity(g/cm2)≥3.8Apparent Porosity(%)<1Flexural Strength (Mpa)>350Compressive Strength(Mpa)>12000Dielectric Constant(1MHZ)2Maximum Use Temperature(°C)S1800
