High Purity Alumina Ceramic 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 corundum crucibles:
1. High purity: Al2O3>99%, high chemical etching resistance;
2. Temperature tolerance, at 1600C for long term application, and at 1800C 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.
