A novel wet polymeric precipitation synthesis method for monophasic β-TCP

Abstract

β-Tricalcium phosphate (β-Ca3(PO4)2, β-TCP) powders were synthesized using wet polymeric precipitation method for the first time to our best knowledge. The results of X-ray diffraction analysis showed the formation of almost single a Ca-deficient hydroxyapatite (CDHA) phase of a poor crystallinity already at room temperature. With continuously increasing the calcination temperature up to 800°C the crystalline β-TCP was obtained as the main phase. It was demonstrated that infrared spectroscopy is very effective method to characterize the formation of β-Ca3(PO4)2. The SEM results showed that β-Ca3(PO4)2 solids were homogeneous having a small particle size distribution. The β-TCP powders consisted of spherical particles varying in size from 100 to 300nm. Fabricated β-TCP specimens were placed to the bones of the rats and maintained for 1–2months. The histological properties of these samples will be also investigated.
