Product Description

Product Description

High Temperature Resistant Cordierite Mullite Sagger Alumina Ceramic Crucible for Glass Melting

1. 99.70% corundum at 1800 ºC, 1650 ºC -1700 ºC. The corundum crucible has good high-temperature insulation and mechanical strength in oxidizing and reducing atmospheres. High thermal conductivity and low thermal expansion rate. It does not react with air, water vapor, hydrogen, carbon monoxide, etc. above 1700 ºC. The maximum short-term operating temperature is 1800 ºC.
2. 99.35% corundum crucible at 1750 ºC, 1600 ºC -1650 ºC in an oxidizing and reducing atmosphere.
3. 85.00% high alumina crucible at 1350 ºC and 1290 ºC has good high-temperature insulation and mechanical strength in oxidizing and reducing atmospheres. High thermal conductivity and low thermal expansion rate. It does not react with air, water vapor, hydrogen, carbon monoxide, etc. It can be used for a long time with little temperature change in the temperature field. The maximum short-term operating temperature is 1400 ºC.

 

Features

High Temperature Resistant Cordierite Mullite Sagger Alumina Ceramic Crucible for Glass Melting

1. The corundum crucible is composed of porous molten alumina, which is strong and resistant to melting.
2. A corundum crucible is suitable for melting NaCl and other substances, but not suitable for melting samples using alkaline and acidic substances such as Na2O2, NaOH, soda ash, potassium carbonate as fluxes (such as K2S2O7).
3. Characteristics of corundum crucible: high temperature resistance, acid and alkali resistance, rapid cooling and heating resistance, and chemical corrosion resistance.
4. The shape of corundum crucible: arc-shaped, cylindrical.
5. Specification of corundum crucible: 5-5000ml.
