9. Various kinds of shape.
Alumina ceramic crucible feature
1. Corundum crucible is suitable for melting samples with anhydrous
Na2CO3 and other weak alkaline substances as flux, but not suitable
for melting samples with Na2O2, NaOH and other strong alkaline
substances and acidic substances as flux (such as K2S2O7 and so on)
2. Resistance to high temperature, acid and alkali, cold and hot,
chemical corrosion
3. The color is white or beige
