Preparation of lanthanum hexaboride by self-propagating high-temperature synthesis for use in accelerator technology

Lanthanum hexaboride was obtained by self-propagating high-temperature synthesis using mechanical activation of LaO-B-Mg charge. The optimal quantitative ratio of the components (wt. %): LaO – 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.
