Grafit crucibles are rib formed clay-graphite crucibles characterised by high refractoriness and good thermal conductivity as well as very good thermal shock resistance and chemical resistance against fluxes. In order to meet the specific requirements of induction furnaces, Morgan Molten Metal Systems has developed a specialised range of clay-graphite crucibles with a specific modified electrical resistivity. This optimises the coupling power of the crucible and avoids the risk of overheating.
Grafit crucibles are suitable for all furnace systems for non-ferrous metal alloys, cast iron and precious metals.
Grafit Typical Metal Casting Temperature
400°C - 1400°C (752°F - 2552°F)
- High refractoriness
- Good thermal conductivity
- Good resistance to chemical erosion
- Good thermal shock resistance

- Good oxidation resistance
Grafit crucibles are coloured black and utilize the suffix G to denote the type.
Grafit crucibles are available in a range of shapes and sizes to suit most end user requirements. Sizes can be made available with pyrometer holes to facilitate measurement of metal temperature. A wide range of pouring lips and spouts is available.
