Characters of corundum/alumina crucible:

 1. High purity: Al2O3 larger than 99%, high chemical etching resistance;

 2. Temperature tolerance, at 1600°C for long term application, and at 1800°C for short term application

 3. Resistant to sudden cold and hot, un-explosive

 4. High density of slip casting
