Graphite Crucibles for Melting Gold 

Graphite Crucible, also called copper melting bag and copper melting, is a kind of crucible made of graphite, clay, silica and paraffin stone as raw materials. Graphite crucible is mainly used to smelt nonferrous metals such as copper, brass, gold, silver, zinc and lead and their alloys.The inner wall of the graphite crucible is smooth, and the molten metal is not easy to leak and adhere to the inner wall of the crucible, so that the molten metal has good fluidity and castability, and is suitable for casting various molds.The graphite crucible is made of natural flake graphite as the main raw material, and is made of plastic refractory clay or carbon binder. It has the characteristics of high temperature resistance, good thermal conductivity, good corrosion resistance, long service life and so on. Product Description Platinum casting crucibles price has good thermal conductivity and high temperature resistance. The thermal expansion coefficient is sm…
