Nanocrystalline Mg-or Sr-containing hydroxyapatite powders were synthesized through low-temperature chemical precipitation. The most significant factor for reduction in particle sizes included adjusting the reaction temperature between 0°C and 50°C. Syntheses products were characterized using several analytical tools to determine purity and influence of added amount (up to 15 mol%) of Mg or Sr on the composition and structure. Qualitative analysis by Fourier transform infrared spectroscopy and low intensity, broad X-ray diffraction peaks indicated the presence of nanocrystalline and/or amorphous hydroxyapatite in all the products. Moreover, a significant decrease in the crystallinity was observed with increasing Mg (up to 2.8 AE 0.3 wt%) and Sr (up to 9.6 AE 1.0 wt%) concentration. N 2 adsorption and scanning electron microscopy characterizations confirmed the nanocrystalline nature of the synthesized products. The synthesized products had nanosized spherical-like particle morphology with the specific surface area ranging from 89 AE 7 to 150 AE 20 m 2 /g.
