3 KG Graphite Crucible. This 3 kg high purity graphite crucible for melting metal has reliable quality. 99.9% high-purity purity allows excellent thermostability and performance, which is not easy to be corroded and oxidized and the groove makes it convenient to use. Non-ferrous metals such as gold, silver, copper, iron and aluminum can be melted in this graphite crucible.
- 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
- Great thermal conductivity this small graphite crucible has excellent thermal conductivity properties, which can highly shorten the melting time and save energy
- Reliable quality using high-quality craftsmanship, our graphite furnace can be used up to a maximum temperature of 1300°C, not easy to crack during high-temperature casting, long service life, pour opening groove design makes it easy to use
- 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
- 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
