Spherical calcium phosphate fine particles, the ratio of Ca/P of which was 5:3 and 3:2, were prepared by ultrasonic spray pyrolysis. ICP analysis showed that as-prepared powders were stoichiometric composition. Hydroxylapatite was obtained from the solution with a Ca/P ratio of 5:3 and tricalcium phosphate was obtained from that of 3:2. The effects of concentration, pyrolysis temperature, and flow rate on particle size, size distribution, and crystal phase were investigated. The relative densities of tricalcium phosphate and hydroxylapatite sintered at 1100°C were about 99% and 97%, respectively.
