The processes of obtaining hafnium diboride by the carbothermic reduction of hafnium oxide by heat treatment in a vacuum furnace and a spark plasma sintering installation have been studied. When the charge was heat treated in a vacuum furnace, hafnium diboride powder was obtained in the temperature range 1500...1700 °C, but it is characterized by the presence of secondary crystalline phases. Monophase hafnium diboride powder with a fine-grained uniform structure was obtained using the spark plasma sintering method at a temperature of 1500 °C.
