摘要: Composition control of hydroxyapatite by post-treatment in an alkaline solution was examined. Non-stoichiometric material having a Ca/P ratio 1.60 treated distilled water (pH 6.5) and concentrated aqueous ammonia 11). The the increased with latter treatment stoichiometric composition (Ca/P=1.67) achieved after six treatments. In contrast, essentially no change found former treatment. powder had high thermal stability nominally composition. incongruent dissolution is discussed.
