FIELD: chemistry.
SUBSTANCE: carbide powder is produced under isothermal conditions in an inert gas atmosphere in an alkali metal halide ion melt, into which a carbide-forming element compound, salt or complex salt thereof, and carbon powder are introduced. Pure powders of metal carbides are produced from the series including Ti, W, V, Ta, Zr, Cr, Mo, Al, Nd, or boron carbide or silicon, ranging in size from about 10 to a few hundred nm of the stoichiometric composition with a low content of trace gases.
EFFECT: increased degree of purification.
