Abstract:
A metal hydroxide solid solution represented by the following formula (1);Mg.sub.1-x M.sup.2+.sub.x (OH).sub.2 1)wherein M.sup.2+ denotes at least one divalent metal ion selected from Mn.sup.2+, Fe.sup.2+, Co.sup.2+, Ni.sup.2+, Cu.sup.2+ and Zn.sup.2+ and x denotes a number in the range of 0.01.ltoreq..times.<0.5,with a crystal habit of an octahedron comprising upper and lower parallel basal planes and six peripheral pyramidal planes, the pyramidal planes consisting of upward-inclined planes and downward-inclined planes which are alternatively located, the ratio of the major axis diameter of the basal plane to the thickness between the upper and lower basal planes (major axis diameter/thickness) being 1 to 9.
