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.

通过碳热还原法合成二硼化铪陶瓷粉末

研究了通过碳热还原氧化铪获得二硼化合铪的过程，包括在真空炉和火花等离子烧结装置中进行热处理。当炉料在真空炉中进行热处理时，在 1500 - 1700°C 的温度范围内获得了以存在次生结晶相为特征的二硼化铪粉末。采用火花等离子烧结法，在 1500°C 的温度下获得了具有细粒均匀结构的单相二硼化铪粉末。
