With 99.9% high-purity graphite and 1.7-1.75g/cm³ high density, our crucible is not easily doped with impurities during the smelting process and can be used for melting high-purity precious metals. This graphite crucible has excellent thermal conductivity properties, which can highly shorten the melting time and save energy. Our graphite furnace can be used up to a maximum temperature of 1300℃. Not easy to crack during high-temperature casting, long service life. Pour opening groove design makes it easy to use. Compared to clay graphite crucibles, our high-purity graphite crucibles can still maintain stability when exposed to strong acids and alkalis and are not prone to be corroded and oxidized. In metallurgy, foundry, machinery, chemical, and other industrial sectors, graphite crucibles are widely used in non-ferrous metal smelting, such as gold, silver, copper, aluminum, and lead.
