ABSTRACT:
A composite metal hydroxide is provided for use as a flame-retardant in a resin or rubber composition. The composite metal hydroxide is a solid solution having the formula (1) Ca.sub.1-x M.sup.2+ x(OH).sub.2. M is at least one member selected from the group consisting of Mg, Mn, Fe, Co, Ni, Cu and Zn and x is in the range of 0.001.ltoreq.x<0.995. Two preferred composite metal hydroxides have the formula (2) Ca.sub.1-x Mg.sup.2+ x(OH).sub.2 wherein x is in the range of 0.001.ltoreq.x<0.995 and the formula (3) Ca.sub.1-x (Mg, Ni, Mn).sub.x (OH).sub.2 wherein x is in the range of 0.001.ltoreq.x<0.995
