Abstract
The process of obtaining hafnium diboride via the carbothermal reduction of hafnium oxide, which involves heat treatment in a vacuum furnace and a spark plasma sintering unit, was studied. When the charge was heat treated in a vacuum furnace, hafnium diboride powder characterized by the presence of secondary crystalline phases was obtained within a temperature range of 1500 – 1700°C. Monophase hafnium diboride powder having a fine-grained uniform structure was obtained using the spark plasma sintering method at a temperature of 1500°C.
