Preparation of Lanthanum Hexaboride by Self-Propagating High-Temperature Synthesis for Use in Accelerator Technology
摘要
Abstract
Lanthanum hexaboride was obtained by self-propagating high-temperature synthesis using mechanical activation of La2O3–B–Mg charge. The optimal quantitative ratio of the components (wt %) of La2O3 43.5, B 37.3, Mg 19.2 was selected, which ensures a more complete combustion reaction. The washing mode of the synthesized product was experimentally selected, which ensures the production of monophasic lanthanum hexaboride, and its properties were studied.
