good thermal conduction, at high temperatures, good wearability, high mechanical strength.

The graphite crucible is the smelting appliances of the non-ferrous metal and rare metal used for the fusion and casting of the non-ferrous metal and rare metal. By the type of heating it can be divided into the fire-burning smelting graphite clay pot and highly pure graphite smelting pot and earthenware crucible of resistance furnace. By the service temperature it can be divided into low temperature crucible below 1200, moderate temperature crucible below 1650 and high temperature crucible below 2000.

The fire-burning graphite clay pot is mainly used for the nonferrous smelting of copper, aluminum, alloy, etc. The resistance furnace highly pure graphite crucible is mainly used for the smelting of gold, silver, and rare metal. The ceramic crucible is mainly used in the laboratory and for the smelting of platinum, gold and rare metals.
