METHOD OF PREPARING SALT MELT CONTAINING LOWER METAL HALIDES Russian patent published in 1999 - IPC

FIELD: inorganic syntheses. SUBSTANCE: invention relates to salt melts of alkali and alkali-earth metals containing lower halides of polyvalent metals such as Ti, Cr, Ni, V, Fe, and others used for galvanic and diffusion coatings. Alkali and alkali-earth metal halides are melted with stable halide of less active metal. Than lower halide of this metal is prepared by electrolysis involving anode made from the same metal as in metal halide being prepared for coating destination. EFFECT: enabled reliable preparation of polyvalent metal halides inclined to disproportionate and be oxidized on heating with no inert gas atmosphere involved. 2 ex
