摘要：
The processes involved in obtaining lanthanum hexaboride by boron thermal reduction using heat-treatment in a vacuum furnace and spark plasma sintering were investigated. Single-phase powder of lanthanum hexaboride was obtained at 1800 – 1900°C with excess boron content in the batch mix equal to 20 wt%. Spark plasma sintering allows the synthesis temperature of the single-phase lanthanum hexaboride powder to be lowered to 1700 and 1600°C with excess boron content 10 and 20 wt.%, respectively, in the batch.
