Hydroxyapatite (HAp) precursors were prepared by chelation of calcium ions with organic phosphonic acid by using calcium nitrate hydrate (Ca(NO_3)_2・4H_2O) and 2-phosphonobutane-1.2.4-tricarboxylic acid (C_7H_<11>PO_9; PBTA) in distilled water in the temperature range of 60-130℃. HAp powder was then synthesized by heating the precursors at various temperatures. HAp precursors were pectized in a three-step reaction. First, calcium ions were chelated with carboxyl groups in PBTA in an early reaction. Second, chelation of calcium ions with phosphonic acid and/or the dehydrated condensation of carboxyl groups with phosphonic acid occurred at and above 80℃. Finally, dehydrated condensation of carboxyl groups proceeded in the range of 100-130℃. The homogeneity of the HAp precursors improved with an increase in their preparation temperature, which accelerated gelation. Powder obtained after heating the HAp precursor prepared at 130℃ (preHAp-130) had a single crystalline HAp phase at 1000℃. In addition, the crystallization temperature of preHAp-130 was 200℃, which was lower than that of HAp precursors prepared using other polymerized complex methods. Powder obtained by heating HAp precursors at and below 800℃ contained carbonate apatite, in which carbonate ions replaced hydroxyl and phosphate sites in the HAp crystal lattice. The Ca/P molar ratio of the HAp powder was higher than that in the stoichiometric composition of HAp (Ca/P=1.67), because the organic components of the HAp precursors were not pyrolyzed; however, the powder obtained by heating preHAp-130 at 1000℃ had stoichiometric HAp composition due to the thermal decomposition of the precursors. The particle size of the HAp powder prepared by heating preHAp-130 decreased with an increase in the heating temperature, and when the HAp particles were heated at and above 800℃, a three-dimensional network with micro and nanopores was formed.
