Products Description




Corundum ceramic crucible, also known as alumina crucible, 99.70% of the corundum crucible is suitable for the temperature of 1650℃- 1700℃. The atmosphere of oxidation and reduction has good high-temperature insulation and mechanical strength. High thermal conductivity, small thermal expansion.Does not react with air, water vapor, hydrogen, carbon monoxide, and so on above 1700℃.Short-term maximum service temperature 1800℃.
99.35% Corundum ceramic crucible has good high-temperature insulation and mechanical strength in oxidation and reduction atmosphere.




Feature
1. Corundum ceramic aluminum 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
