Graphite crucibles for the jewelry industry
Product Description
Graphite crucibles, as well as other graphite equipment, are widely used in jewelry production, for gas analysis and for induction furnaces, due to the unique specific properties of graphite.

Firstly, graphite is a heat-resistant material that ensures normal performance up to a temperature of 600-800 in an oxidizing environment and up to 2500 C in a protective gas environment or vacuum.

Secondly, graphite is a material resistant to thermal shocks, as well as cyclic thermal shocks, which makes it possible to use it without preheating before contact with molten metal, which is important for the manufacture of molds, molds and other form-building products.

Thirdly, the graphite of the crucible promotes the reduction of metal oxide to metal, forming an easily volatilized CO compound with the oxygen of the oxide, which facilitates the purification of the metal.

Fourthly, graphite is a more stable and predictable material compared to any type of ceramics. Since ceramic crucibles are characterized by sudden cracking and spilling of molten metal, which practically does not happen when using graphite crucibles. During cyclic melting, graphite crucibles burn out to a certain state, after which the foundry operator can determine by eye that the crucible is unsuitable for further use.

Absolutely any options for making crucibles are possible, both for the jewelry industry and for gas analysis and induction furnaces. We also make crucibles according to customer drawings.
