Notes:
Nanosized hydroxyapatite(HAp) was synthesized hydrothermally and influence ofprocessing parameters, such as reaction temperature and time, pH, and Ca/P ratio, on the phasestability of HAp was evaluated after pressureless sintering at 1250°C in air. The highest stabilitywas achieved from the powder obtained at a processing condition for the lowest solubility of Ca2+,which corresponds to temperature close to 200°C, time 〈4h, pH〉9.0, and Ca/P = 1.67. The stabilityof nanosized HAp in HAp/3Y-TZP composites was slightly inferior to commercial one, but theinvolvement of hydrothermally synthesized HAp improved sintered density of the composites andstability of t-ZrO2 phase in the composites
