Alumina crucible: 1. High purity>99.7% 2 Max service temperature 1800 degree 3 Good thermal shock 4,High density

Alumina crucible is used for testing laboratory and a variety of  industrial analysis.  Alumina ceramic crucible and corundum crucible include: arc alumina crucible, square alumina crucible, rectangle alumina ceramic crucible, column ceramic crucible and a variety of shaped alumina ceramic crucible.

Characters of alumina crucible and corundum crucible:      1. High purity: Al2O399%, high chemical etching resistance;      2. Temperature tolerance, at 1600 for long term application, and at 1800 for short term application;      3. Resistant to sudden cold and hot, un-explosive;      4. High density of slip casting, high purity alumina crucible, specifications of 99% corundum crucibles: 5ml 10ml 15ml 20ml 25ml 30ml 50ml 100ml 150ml 200ml- 2500ml. Characters of corundum crucible:  1.
