Fine powder of dysprosium hydride is mixed with silicon in a ratio of 25.68 wt. % Si and 74,32 weight. % Dy. Under the conditions of Example 1, disilicide dysprosis is obtained. Analysis and characteristics of the product. calculation- found Content Dy, weight. % 74,3274,8 Si content, weight. %: 25.6824.9 No hydrogen. X-ray phase analysis. Single-phase disilicide dysprosy DySia of rhombic structure was obtained. As can be seen from the examples, the proposed method allows to obtain pure and odiofasic compounds of silt-free elements, which provides its advantages over lime lime. Formula and 3 about b e and e and The method of obtaining silt compounds from a series of borides, silicides, carbides and nitrides of metals III, IV, V groups of the periodic system and groups of lantaiids, preparation of a mixture, including metal hydride and non-metal, pressing, ignition mixtures of tungsten coil and synthesis in combustion relissim, characterized in that, in order to achieve a higher purity of the product, in the initial mixture the metal and nonmetal hydride is taken in a stoichiometric ratio and the compression mixture is preheated to 600-800 ° C.
