Abstract (en)
[origin: CA2027257A1] The invention relates to a process for the preparation of finely divided microcrystalline-to-amorphous metal and/or alloy powders aid of metals and/or alloys in the form of colloidal solutions in organic solvents, which is process is characterized in that in inert organic solvents metal salts individually or in admixture are reacted with alkaline metal or alkaline earth metal hydrides which are maintained in solution by means of organoboron or organogallium complexing agents, or with tetraalkylammonium triorganoborohydrate, respectively.
