Abstract:
A process for producing a nickel composite particle having a layer of a nickel-containing spinel on at least a part of a surface of a nickel particle, said process comprising:forming fine liquid droplets from a solution comprising (a) at least one thermally decomposable compound of nickel and (b) at least one thermally decomposable compound of a metal capable of forming a spinel together with nickel; and heating the liquid droplets at a temperature higher than the decomposition temperatures of the thermally decomposable compound of nickel and the thermally decomposable compound of a metal capable of forming a spinel together with nickel to form a nickel particle and simultaneously deposit a layer of a nickel-containing spinel on at least a part of a surface thereof.
