Hydroxyapatite (HA) crystals with arambola-like structures were prepared by supersaturated urea-assisted solvothermal synthesis using double-facile surfactants. The products were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, thermal gravimetric analysis, and scanning electron microscopy. Results revealed that the morphologies of the products, including micro-hexagonal prism, carambola-like structures, and microspheres could be well tailored by regulating the double-facile surfactants and reaction time. Na(2)EDTA exhibited a slight inhibitory effect on HA formation. Stearic acid adsorbs on the surface of HA to form a layer with long chains and act as mechanical barrier, indicating its excellent dispersibility. (C) 2019 Elsevier B.V. All rights reserved.
