       Cylindrical 99% Alumina Ceramic Crucible For High Temeprature Furnace

 

Introduction of alumina ceramic crucible :

Corundum ceramic crucible, also known as alumina crucible, 99.70% corundum crucible in 1800℃1650℃- 1700℃ corundum crucible in the atmosphere of oxidation and reduction, has a 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

85% High alumina crucible 1305℃ 1290℃ has good high temperature insulation and mechanical strength in oxidation and reduction atmosphere.High thermal conductivity, small thermal expansion.It doesn't react with air, water vapor, hydrogen, carbon monoxide, etc.It can be used for a long time under the condition of little change of temperature field.Short-term maximum service temperature 1400℃

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
