| Properties | 99.5% | 99.0% | 95.0% | 60.0% |
| Long time operating temperature | 1700℃ | 1600℃ | 1350℃ | 1100℃ |
1、99.5% alumina
Aluminum oxide crucible has good high-temperature insulation and mechanical strength in the oxidizing and reducing atmosphere at 1650°C – 1700°C. Large thermal conductivity and small thermal expansion. Does not react with air, water vapor, hydrogen, carbon monoxide, etc. above 1700°C. Short-term rated use temperature 1800℃.
2、99.0% alumina
It can be used for a long time in the oxidizing and reducing atmosphere at 1600℃, but should not be used over 1650℃.
3、95.0% high alumina
1350°C high alumina crucible in an oxidizing and reducing atmosphere, does not react with air, water vapor, hydrogen, carbon monoxide, etc., short-term rated use temperature 1400°C.
4、60.0% high alumina
It can be used in an oxidizing and reducing atmosphere at 1100°C for a long time, but should not be used beyond 1150°C.
