SULPHUR-CONTAINING NICKEL PARTICLE AND METHOD FOR PRODUCING THE SAME

PROBLEM TO BE SOLVED: To provide a method for suitably producing sulphur-containing nickel particles in which the sulphur is almost uniformly disposed over the entire surface of the nickel particles.SOLUTION: The method for producing the sulphur-containing nickel particles includes: preparing a raw material aqueous solution containing nickel ions; producing a composite of nickel and an organic compound in the solution by adding the organic compound which functions as a reducing agent in the raw material aqueous solution; adding an alkali metal salt of polycarboxylic acid in the raw material aqueous solution in which the composite is formed; adding an sulphur feed material consisting of dispersed sulphur powders in the raw material aqueous solution added with the alkali metal salt of the polycarboxylic acid; controlling the raw material aqueous solution into which the sulphur feed material is added to the basic so that the reduction reaction of the nickel is induced; and recovering the sulphur-containing nickel particles formed by the reduction reaction.
