Hydroxyapatite powders were prepared by calcining freeze-dried mixtures of calcium acetate and tri-ethyl phosphate, in which no calcium phosphate was formed. Results of X-ray powder diffraction were compared with those of commercially available hydroxyapatite powders. The optimum operating conditions were determined by varying factors such as calcination temperature, Ca/P ratio of the solution, and retention time.
