FIELD: technology for producing ultra-high-temperature ceramic matrix diborides of heat-resistant metals.
SUBSTANCE: method for obtaining solutions of hafnium, zirconium, tantalum, niobium and tungsten borohydrides by reacting lithium borohydrides in a medium of saturated hydrocarbons in presence of a catalyst during mechanochemical activation in an inert gas atmosphere, followed by filtration of the final product with provision of a differential pressure of inert gas on the filter and a solution of heat-resistant metal borohydride.
EFFECT: expansion of the group of metals used to obtain heat-resistant metal bohydrides, as well as ensuring the fire and explosion safety of the process.
