Corundum crucibles, saggers, burners and other products have the characteristics of not easy to crack, not easy to drop slag, and long service life.
1. Corundum crucible is composed of porous fused alumina, which is firm and refractory.
2. The corundum crucible is suitable for melting NaCl, etc., and is not suitable for melting samples with alkaline substances such as Na2O2, NaOH, soda ash, potassium carbonate, and acidic substances (such as K2S2O7, etc.).
3. The characteristics of corundum crucible: high temperature resistance, acid and alkali resistance, rapid cooling and heat resistance, chemical corrosion resistance.
4. The shape of the corundum crucible: curved, cylindrical.
5. Specifications of corundum crucible: 5-1000ml.
