Noltina‘s 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, NOLTINA 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.



Noltina‘s Grafit crucibles are suitable for all furnace systems for non-ferrous metal alloys and precious metals with melting temperatures between 400°C and 1400°C.
