product description

Graphite crucible is a common tool for gold foundries. It has become the best choice in this field due to its unique characteristics.

the high thermal conductivity of graphite crucible: the thermal conductivity of graphite crucible is much higher than that of other refractory materials. It can promote high-speed heat transfer, thereby shortening the melting time of gold and reducing energy consumption.

chemical inertness of graphite crucible: during the melting process of gold, a dense oxide layer is formed on the surface of graphite crucible to prevent metal leakage, reduce gold loss and ensure its purity.

Another thing to mention is the thermal shock resistance of graphite crucible: graphite crucible has a low thermal expansion coefficient, can withstand sudden cooling and heating conditions, and has a longer service life than ordinary crucibles. At the same time, graphite crucible also has strong corrosion resistance and is resistant to trace impurities (such as copper and silver alloy elements) in molten gold.
