Mini Cylinder Graphite Crucible 99 % Alumina Ceramic For Tube Muffle Furnace
99% Alumina Ceramic Mini Cylinder Crucible For Tube Muffle Furnace
Application of alumina ceramic cylinder crucible:
Under normal circumstances most of the material will be analyzed and used to bake saggar made from different materials within the system first and then placed into the crucible or analysis or fired for heating equipment. According to the speed and heating equipment and temperature characteristics of the product with drawal, some are faster and some are slower. Because of the crucible and saggar made from different materials with thermal expansion materials. Crucible easily lead to excessive heating or cooling cracking so it is best to slow down and saggar made from different materials. This will extend the life of crucible and saggar made from different materials.
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
