Hydroxyapatite nanoparticles were synthesized by controlled precipitation method in the aqueous phase. The synthesis was carried out in the presence of nonionic surfactant Brij 30 to restrict the growth of nanoparticles. Synthesis was carried out with a concentration of Brij 30 in the range of 0.05-0.25 M. Nanoplates with sizes of 60-130 nm were formed at Brij 30 concentration in the range of 0.05-0.10 M. Increasing the surfactant concentration up to 0.15 M promoted the formation of nanorods with the average length of 30 nm and 10 nm in diameter. The length/diameter ratio of nanorods increased with increasing surfactant concentration, crystal growth occurs predominantly along the c-axis. The average length of nanorods increased from 50 nm to 70 nm in the range of Brij 30 concentration of 0.20-0.25 M. The obtained hydroxyapatite nanoparticles can be used for medical purposes due to high dispersion and phase purity.
