Yinxuan Graphite Crucible Anti-oxidation For Precious Metal Smelting

Precious metal smelting is classified to primary smelting and refining. Primary smelting indicates to get low purity precious metal through smelting minerals, where large size low grade graphite crucibles are applied. Refinery means getting high purity precious metals through smelting low purity metals, where graphite crucibles are needed with high purity, high bulk density, low porosity and good strength.

Yinxuan Graphite Crucible Anti-oxidation for Precious Metal Smelting

Raw Material Selection.

Graphite crucibles for primary smelting are usually machined by two impregnated medium grain graphite material, while three impregnated isostatic or molded graphite material applied for refinery used graphite crucible.

Products Machining.

There is no high precision requirements for primary smelting graphite crucibles, while strict requirements for refining graphite crucibles with precise dimensions and polished surface. Zibo Yinxuan graphite crucibles could meet the design requirements for both primary smelting and refining.
