Description

A graphite crucible is typically used for melting non-ferrous, or non-iron, metals such as gold, silver, aluminum or brass.

Graphite  crucible 

Different specification available 

Features: 
High purity, fine grain, good performance of electrical conductivity and thermal conductivity, high density, good corrosion resistance, thermal shock resistance, thermal stability, high mechanical strength, low permeability, and good oxidation resistance. The raw material is capable of producing various semiconductor molds and radio tube.
