FIELD: manufacture of metal powders used, mainly in pastes and suspensions designed for voltaic cells.
SUBSTANCE: method comprises steps of providing liquid bath in reactor; preparing mixture containing metal carbonyl; adding such mixture into liquid bath; decomposing metal carbonyl in liquid bath for forming metallic particles of predetermined size in order to prepare liquid dispersion of metallic particles in liquid bath. According to invention mixture containing metal carbonyl is added in the form of gaseous mixture produced by mixing gaseous metal carbonyl with inert gas-carrier; bubbling it into liquid bath for decomposition at least of part of gaseous metal carbonyl. Prepared liquid dispersion of metallic particles in liquid bath has preset viscosity.
EFFECT: possibility for preparing powder particles of uniform structure, enhanced effectiveness of method due to elimination of several standard treatment stages.
