Carbon graphite crucible material is made of special high purity, high strength and high density graphite material, which is made by high precision CNC processing equipment.

china graphite crucible sizes are various, ranging from 250g to 800kg. The most seen ones are 2kg/3kg/4kg/5kg/6kg/10kg graphite crucibles. It is mainly used for melting precious metals, gold, silver, copper, aluminum, and various kinds of moulds.

Graphite crucible for melting has high temperature resistance, strong thermal conductivity, special glaze layer and dense molding material, which greatly improves the corrosion resistance of the product and extends its service life. As an experienced graphite crucible supplier, our company provide mass purchasing and custom services as needed.

How To Temper A Graphite Crucible

Graphite crucible in the production of the main material is graphite, including clay, aggregate and other components. The graphite crucible temperature limit mainly depends on the graphite material, but also is affected by other materials.

The graphite crucible melting point is 3850±50℃ and the boiling point is 4250℃. Its strength increases with the temperature. At 2000℃, graphite strength is doubled. After ultra-high temperature arc burning, its weight loss is very small, thermal expansion coefficient is also very small.
