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.
