High pure graphite crucibles

Mainly used in jewelry industry for precious metals smelting,

Using high purity ,high strength,high density graphite as raw material,  extremely low ash content  to ensure that the precious metals in the smelting is not contaminated.

Graphite crucible has good thermal conductivity and high temperature resistance. In the process of high temperature use, its thermal expansion coefficient is small, and it has certain strain resistance to rapid heat and rapid cooling.It has strong corrosion resistance to acid and alkaline solution and excellent chemical stability.In metallurgy, casting, machinery, chemical and other industrial sectors, widely used in the smelting of non-ferrous metals and the alloys.
