Abstract
Mixed calcium-cobalt phosphates. of formula Ca3-xCOx(PO4)2 where 0 les s-than-or-equal-to x less-than-or-equal-to 1.1, were prepared by copre cipitation. Physicochemical characterization showed that the solids ob tained resulted from substitution of some Ca2+ ions by Co2+ ions in th e beta-Ca3(PO4)2 Structure. The solubility limit of cobalt in this str ucture corresponds to x = 0.31. This limit was observed to coincide wi th the maximum activity in isopropanol decomposition.
