Technical specifications
Niobium crucibles are made of niobium hot-rolled high-quality NBSH-0, NBSH-00 plates by machining and pressing. Niobium crucibles are used in the melting of rare earth metals as a heat-resistant container for the needs of metallurgy and machine building, as well as for annealing and sintering of powdered raw materials (nonmetals and metals) in a reduction atmosphere.
