Product Description

High pure graphite crucible gold melting graphite crucible

Graphite materials are widely used for making crucibles, which provide a non-reactive vessel that will survive the high temperature in metal melting and processing. Graphite crucible is used for melting non-ferrous and metals such as gold, silver, aluminum or brass, ect.

 

There are different types of crucibles. We could manufacture the graphite crucible according to your drawing. Or if you have requirement about the crucible capacity, dimension, we could offer suggestion and produce based on your demands.
