Abstract
The production of zirconium and hafnium nitrides and halides comprises synthesis in a closed reactor in a furnace with two heating zones. The synthesis stage is followed by purification in the furnace, and takes place at a uniform temperature in the cold zone. The purification zone operates at a temperature gradient. - (Dwg.0/1)
