Abstract

Size controlled hydroxyapatite powders with nanometer sizes were directly prepared by high temperature flame spray pyrolysis. Nanosized hydroxyapatite powders were formed from the evaporated vapors by chemical vapor deposition process. The composition ratio of calcium and phosphorous components was 1.67. The mean size of the hydroxyapatite powders increased from 21 to 81 nm when the concentration of spray solution was changed from 0.05 to 2 mol/L. Sintering of the nanosized hydroxyapatite powders occurred at a temperature of 1000°C, and grain growth increased with increasing the sintering temperatures. The mean grain sizes of the pellets sintered at temperatures of 1200, 1300, and 1400°C were 0.93, 4.9, and 18 μm.
