Abstract:
Co(II) oxide product made by a process comprising:(1) reacting crystallized basic cobalt compounds of the general formulaCo[(OH).sub.2 ].sub.a [O].sub.b [CO.sub.3 ].sub.c, where 1.ltoreq.a+b+c.ltoreq.1.5,with aqueous and/or alcoholic solutions of an organic compound containing at least one carboxyl group;(2) separating solids from the suspension which results from the reaction;(3) calcining the resulting solids at 500-800.degree. C. whereby Co metal forms on the surface of the Co(II) oxide;wherein the crystallized basic cobalt compounds have particles sizes within a range of 2 to 20 .mu.m, and wherein the reaction is initially conducted at room temperature for 0.5 to 1.5 hours and then at 70 to 90.degree. C. to completion.
