Abstract
A theoretical calculation was conducted to determine the potential for and the conditions under which mineral phases may form. It has been established that under these conditions the formation of a mixture of calcium phosphates is possible, with hydroxyapatite being the most stable phase. Based on the calculated data, a synthesis was carried out, as a result of which it was established that the resulting sediments were represented by the phases of hydroxyapatite, octacalcium phosphate and brushite. It was found that the synthesized mixture of calcium phosphates can be used to create dense ceramics. Thus, the range of use of synthesized materials is expanding. It has been proven that in an SBF solution a calcium phosphate layer is formed on the surface of the samples, which indicates the bioactivity of the samples. The prospect for further development of the topic is the use of ceramics as materials for replacing bone defects or a biologically active layer on the surface of implants.
期刊介绍：
Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques publishes original articles on the topical problems of solid-state physics, materials science, experimental techniques, condensed media, nanostructures, surfaces of thin films, and phase boundaries: geometric and energetical structures of surfaces, the methods of computer simulations; physical and chemical properties and their changes upon radiation and other treatments; the methods of studies of films and surface layers of crystals (XRD, XPS, synchrotron radiation, neutron and electron diffraction, electron microscopic, scanning tunneling microscopic, atomic force microscopic studies, and other methods that provide data on the surfaces and thin films). Articles related to the methods and technics of structure studies are the focus of the journal. The journal accepts manuscripts of regular articles and reviews in English or Russian language from authors of all countries. All manuscripts are peer-reviewed.
