graphite crucibles and stoppers


Precious metal smelting is classified to primary smelting and refining. Refinery means getting high purity precious metal through smelting low purity metals, where graphite crucibles are needed with high purity, high bulk density, low porosity and good strength.

Top Reasons to our Graphite Crucible

Graphite accessories for experimental equipment are made of high-quality, high-strength, high-purity, and high-density graphite, with a smooth surface and no pores. They have the characteristics of uniform thermal conductivity, rapid heating, high temperature resistance, and acid alkali corrosion resistance; In addition, special coating treatment can be used. After surface treatment, under long-term high-temperature heating, there will be no phenomenon of powder shedding, threshing, damage, and oxidation. It can withstand strong acids and alkalis, is durable, beautiful, and does not rust.
