3. Features of alumina crucibles

1. High purity: Al2O3≥99%, high chemical etching resistance;

2. Temperature tolerance, at 1600°C for long term application, and at 1800°C for short term application;

3. Resistant to sudden cold and hot, un-explosive;

4. High density of slip casting, high purity alumina crucible,


Alumina or Aluminium Oxide(Al2O3) in its various of levels of purity is used more often than any other types of advanced ceramic materials. Alumina cermaic is a kind of structural ceramics, with insulation resistance, voltage resistance, high strength, good thermal conductivity, dielectric loss, stable electrical performance characteristics. Used in electronic ceramic substrates, ceramic electrical insulation, vacuum devices, spark plugs etc.
