Wide Application: 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. Stable Properties: 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. Reliable Quality: Using high-quality craftsmanship, 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. Great Thermal Conductivity: This small graphite crucible has excellent thermal conductivity properties, which can highly shorten the melting time and save energy. High Purity Graphite: With 99.9% high-purity graphite and 1.8-1.82 g/cm³ high density, our crucible is not easy to be doped with impurities during the smelting process and can be used to melting high-purity precious metals.
