概要	Preparation of hydroxyapatite was carried out by a homogeneous precipitation technique using hydrothermal reactions of Ca(EDTA)2- and PO43- at 130–250°C and pH 4–10. Hydroxyapatite and monetite were formed above pH 6 and below pH 4, respectively. Needle-like hydroxyapatite was formed at high temperatures above 130°C. The length of the needle-like hydroxyapatite crystal increased with increasing working solution pH and temperature.
