Biphasic Calcium Phosphate Composite for Biomedical Applications

Abstract

The paper describes the preparation of the biphasic (hydroxyapatite (HA) and tricalcium phosphate (TCP)) nanostructured calcium phosphate composite. The product was chemically synthesized from the solution which contained calcium acetate Са(СН3СОО)2 (0,167 mМ), sodium dihydrogen phosphate NaH2PO4 (0,1 mМ), sodium hydrocarbonate NaHCO3 (0,02 mM). The calcium phosphate composite was formed at pH=11 with and without the addition of carbonate ions. The samples were analyzed using X-Ray diffraction after the heat treatment at 900C for 1 h. The derived material contained HA and TCP phases with their contents change depending on the concentration of the carbonate ions in the solution. The mean crystallite size of the HA phase in (121) plane is 12 – 14 nm. Further studies will be directed to the using of the derived composite for the biomedical applications.
