Description
ceramic crucible:
1.Al2O3>=99.7%
2.Density,3.85g/cm3.
3.Flexural strength, 360Mpa.
4.Max. temp.1800.
Features fo the ceramic crucible:
1. High purity, (Al2O3≥99.7%; Fe2O3≤0.1%; SiO2≤0.2%.)
2. High chemical etching resistance of the ceramic crucible.
3. Temperature tolerance, 1600°C for long term application; 1800°C for short term application with the ceramic crucible.
4. Resistant to sudden cold and hot, un-explosive of the ceramic crucible.
5. High density of slip casting from ceramic crucible.
