Abstract	Calcium-deficient hydroxyapatite (CDHAP) and metal-substituted hydroxyapatite (Me-HAP) are prepared by chemical deposition from solutions of relevant compositions. Powderlike samples are studied by X-ray diffraction (XRD), electron probe microanalysis (EPMA), infrared spectroscopy (IR) and scanning electron microscopy (SEM). The XRD and EPMA data show that under certain conditions calcium-deficient hydroxyapatite CDHAP could be produced with a calcium to phosphorus ratio of Ca/P = 1.43 and with an average nanocrystal size of ∼50 nm. The calcium deficiency in the hexagonal structure of Me-HAP is also retained upon the partial replacement of calcium with Zn and Cu atoms with smaller radii. The lattice parameters and the average sizes of the nanocrystals of Me-HAP are lower as compared with undoped CDHAP.
