摘要

beta-Tricalcium phosphate (beta-Ca-3(PO4)(2), beta-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 degrees C the crystalline beta-TCP was obtained as the main phase. It was demonstrated that infrared spectroscopy is very effective method to characterize the formation of beta-Ca-3(PO4)(2). The SEM results showed that beta-Ca-3(PO4)(2) solids were homogeneous having a small particle size distribution. The (beta-TCP powders consisted of spherical particles varying in size from 100 to 300 nm. Fabricated (beta-TCP specimens were placed to the bones of the rats and maintained for 1-2 months. The histological properties of these samples will be also investigated.
