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 900C 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.
