The paper presents results of studies carried out on process crystallization of calcium ions precipitation in water with the use of ammonium dihydrogenphosphate NH4H2PO4 under alkaline conditions (pH = 9). Experiments were carried out in the continuous crystallizer with an internal circulation of suspension. The influence of calcium ions concentration in the raw material, temperature and residence time on the mean size of hydroxyapatite crystals (Lm = 2.0-5.0 mm) were evaluated. The rates of hydroxyapatite crystals growth (Grc = 7.1l0-10 - l.410-9 m/s) were evaluated from the crystal size distribution.
