Abstract
The products formed at the reduction of silver, copper, nickel and bismuth carboxylates were investigated by methods of chemical, X-ray phase, differential thermogravimetric analyses and electronic microscopy at heating in the environment of high-boiling organic liquid. It was shown that powders of silver, copper, nickel, bismuth and of alloys of these metals of the submicron size could be obtained by the way of reduction of these metals carboxylates by ethylene glycol and benzyl alcohol. Structural morphological features of powders obtained, as well as the influence on these parameters of the length of the methylene chain of the starting carboxylate, its morphology and the process of doping by cations of other metals were investigated.
