Abstract The present research is intended to provide a base for further investigation of the chemistry of whitlockites, and Zn-whitlockite, in particular. Zinc-containing whitlockite Ca10Zn10H2(PO4)14 was successfully prepared at room temperature by means of a chemical reaction between Ca(NO3)2, Zn(NO3)2 and (NH4)2HPO4 at a pH around 11.0. The X-ray pattern of the compound is that of magnesium-iron whitlockite Ca18(Mg,Fe)2H2(PO4)14 or, in a broader aspect, solid solutions of the composition Ca20−xMe2+xH2(PO4)14, structurally related to tricalcium phosphate. It is suggested that the compound, alone or as an additive to hydroxyapatite, might be suitable for the preparation of biodegradable orthopedic implants containing zinc.
