High Purity Graphite Crucible 3 Kg Graphite Furnace Single Ring Graphite Crucible Metal Graphite Jewelry Casting Tools

[HIGH PURITY GRAPHITE]- With 99.9% high-purity graphite and 1.8-1.82g/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℃. 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.
