~Graphite crucible, good resistance to high temperature performance remained stable under high temperature, the quantity of heat and cold are small and can be neglected;Graphite lubricant is better, the solidification process of liquid metal bonding in the lining of the crucible

1. Good thermal stability: according to the using conditions of graphite crucible, snap hot cold  special formula. 
2. Good corrosion resistance, impact resistance performance, to ensure the reliability of product quality. 
3. Good resistance to strong acid, strong alkali. 
4. Good heat transfer performance, can greatly shorten the melting time  to save energy. 
6. Less than 300 pp ash ensure that precious metals in smelting is not contaminated

Widely used for Precious metals smelting, jewelry casting industry
Capacity :from 1kg-30kg Can be customize
