Summary

The production of zirconium carbide under industrial conditions was investigated.

It is shown that the optimum process parameters, yielding a product with a maximum combined-carbon content, are: reduction of a stoichiometric charge composed of zirconium dioxide and carbon black in a resistance furnace with a graphite heating element at a temperature of 2200°C and a holding period of 60 min in a hydrogen atmosphere. The charge is rammed, in batches weighing 1500–2300 g, into graphite cartridges. It is demonstrated that zirconium carbide can be produced also in a converted-gas atmosphere or without a protective atmosphere.
