Advantages:
Our silicon carbide graphite crucible has the following characteristics:
1. Higher thermal conductivity: Shorten the time of smelting, save energy;
2. Higher strength: Shaped by isostatic pressing, internal structure without defects, high physical strength;
3. Better oxidation resistance: Unique antioxidant design, and use high purity raw materials to protect graphite, high oxidation resistance; It’s 5~10 times of ordinary graphite crucible.
4. Anti erosion: low porosity, special additives, effectively resist the corrosion of slag and other melts.
5. long life: Crucible’s life can be 3-5times longer than normal graphite crucible.
