Noltina Grafit Crucibles

Noltina s Grafit crucibles are CLAY-GRAPHITE crucibles. They are roller formed crucibles characterized by high refractoriness and good thermal conductivity as well as very good thermal shock resistance and chemical resistance against fluxes. Further essential characteristics are the high mechanical strength and good oxidation resistance. CLAY-GRAPHITE crucibles are suitable for all furnace systems for non-ferrous metal alloys and precious metals with melting temperatures between 400 C and 1400 C. 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.
