Abstract

A method for producing titanium dioxide (TiO2) containing hydroxyapatite (HA) crystallite isproposed. Solutions of CaCI2+H3PO4 and TiCL4+HCI combined with KOH are used to precipitatefirst the HA and then the TiO2.The precipitate is then sintered between 900°C and 1000°C for 18 to48 hours. X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Energy DispersiveX-ray Analysis (EDX) and scanning electron microscopy (SEM) have been used to determine thecrystallinity, the chemical composition and structure of the samples.
