FIELD: inorganic syntheses. SUBSTANCE: initial compounds - rare-earth metal oxides or chlorides and boron are subjected to heat treatment at 850-1100 C in presence of lithium hydride (reducing agent). Reaction mixture is then washed with water and dried to produce finely dispersed product. EFFECT: simplified process due to lower temperature and avoided pollution of product with by-products. 3 ex
