Product Description

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.
