Classification of graphite crucibles:

Crucibles can be divided into three categories: graphite crucible, clay crucible and metal crucible. We can produce two kinds of graphite crucible: machined graphite crucibles and graphite clay crucibles.

1) Machined graphite crucible, also known as high-purity graphite crucible, mainly machined with high purity and high density graphite materials, such as molded graphite material, isostatic graphite material. Mchined graphite crucibles can be devided to steel melting crucible, copper melting crucible, gold melting crucible and analysis crucible, due to the meterials melted. Also we can produce graphite ark for different uses.

2) graphite clay crucible, also known as SiC graphite crucible. Because it is main content of this crucible are silicon carbide (SiC) and graphite. Mainly used for melting copper, aluminum and other common metals. The cost of this kind of crucibles is relatively low, with large capacity of molten metal. The crucible molding method is mainly pressure forming method.

Application:
Due to different performances, applications, different application conditions, the use of raw materials, production methods, technology and product specifications are also different. Graphite crucibles are widely used in the smelting of alloy tool steels and the smelting of non-ferrous metals and their alloys in metallurgy, foundry, machinery, chemical and other industrial areas because of their superior properties.
