| Summary: | This article shows the results of a study on a biocomposite material based on calcium phosphate doped with
ZnCl and AgNO3. Calcium phosphates are mainly used in dentistry and orthopedics due to their excellent biocompatibility, osteoconductive properties and similarity to the inorganic components of human bone. The main objective of the study is to investigate the morphology, elemental and phase composition, and physicochemical properties of the obtained material. The test material is obtained in the form of a suspension and subjected to ultrasonic treatment. The microstructure and phase composition of the obtained biocomposites are studied by SEM, XRD, FTIR methods. It is possible to obtain dicalcium phosphate dihydrate (DCPD) by the presented methods, and the results demonstrate a partial replacement of calcium atoms by zinc atoms. Xray phase analysis shows that Ca(HPO4) (H2O)2 phases as well as CaZn2 (PO4)2 (H2O)2 and AgCl phases were formed during the reaction. Fourier transform infrared spectroscopy revealed that the obtained samples contain the groups HPO42 and PO43, with the group PO42 replacing the group CO32. The biocomposite materials could be of great interest in the biomedical field, including the development of coatings that prevent or delay the development of bacterial biofilm.
