Characteristics of Ceramic Crucible / Corundum Crucible Products:
High purity, chemical resistance, good corrosion resistance.
Good temperature resistance, long-term use at 1600 degrees Celsius, short-term 1800 degrees Celsius.
It has good quench and heat resistance and is not easy to burst.
High density of grouting, high purity alumina crucible 99% corundum ceramic crucible.
Application of Ceramic Crucible :
Corundum crucible is composed of porous molten alumina, which is strong and melt-resistant.
Corundum crucible is suitable for melting samples with weak alkaline substances such as anhydrous Na2CO3, but not strong alkaline substances such as Na2O2, NaOH and acidic substances such as K2S2O7.
