Product Description
Graphite Crucible
Graphite crucibles are widely used in the smelting of precious metals and the smelting of non-ferrous metals and their alloys in metallurgy, foundry, machinery, chemical and other industrial areas because of their superior properties. And has a good technical and economic effects.
Graphite crucible has more sizes, and not restricted to the production scale, quantity and smelting materials, it can be produced to any size, any quantity, and can ensure the purity of the smelting materials.
The Material of Graphite Crucible:
The material of Graphite Crucible include Fine-grain Graphite, High Pure Graphite, and Isostatic Graphite. We will choose the material to produce the Graphite Crucible based on customer's different application, working temperature, thermal shock property, acid-base property.

Graphite materials has the following characteristics:
1. High temperature resistance.
2. Good thermal conductivity.
3. Good corrosion resistance, long service life.
4. Small coefficient of thermal expansion, and it has a certain strain resistance to quench and heat.
5. Stable chemical property and hard to react.
6. Smooth inner wall, molten metal is not easy to leak and adhere to the inner wall of the crucible.
