1.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 graphiteclay pot and highly pure graphite smelting pot and earthenware crucible of resistance furnace.
2.By the service temperature it can be divided into low temperaturecrucible below 1200, moderate temperature crucible below 1650 and high temperaturecrucible below 2000. The fire-burning graphite clay pot is mainly used for the nonferrous smelting ofcopper, aluminum, alloy, etc.
3.The resistance furnace highly pure graphite crucibleis mainly used for the smelting of gold, silver, and rare metal. The ceramiccrucible is mainly used in the laboratory and for the smelting of platinum, gold and rare metals.
