title: Synthesis and characterisation of nanohydroxyapatite using an ultrasound assisted method.
abstract: Nanostructured hydroxyapatite (HAP) was prepared by a wet precipitation method using Ca(NO(3)) and KH(2)PO(4) as the main material and NH(3) as the precipitator under ultrasonic irradiation. The Ca/P ratio was set at 1.67 and the pH maintained at a minimum of 9. The temperature conditions and ultrasound influences were investigated using X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM) and Fourier transform infrared spectroscopy (FT-IR). The results showed that Nano-HAP can be obtained by this method and the particles were achieved to around 30 nm.
