Original article
Abstract: The article discusses the possibility of obtaining hardened bioceramics based on fluorapatite. Composite materials were obtained in two ways. In the first case, by mechanical synthesis of nanostructured hydroxyapatite obtained by precipitation from a solution with an estimated amount of doping components (calcium fluoride, nonstoichiometric titanium oxide, or zirconium dioxide) and subsequent high-temperature treatment. In the second case, the mechanochemical reinforcement was carried out with the direct introduction of a reinforcing component (non-micrometeometric titanium oxide or dicyrconium) into ultrafine fluorapatite obtained by precipitation from solution. The synthesized samples are certified using modern physico-chemical analysis methods. The influence of the qualitative and quantitative composition of the composite on the sintering processes and the strength characteristics of the studied samples is shown. It has been experimentally established that materials meeting the required functional characteristics can be obtained by hardening fluorapatite with zirconium dioxide in an amount of 5 wt.% as well as due to the joint reinforcement of hydroxyapatite with calcium fluoride and titanium oxide in equal amounts (15 wt.%). Composite materials of the specified composition are thermally stable, have a constant phase composition, a dense uniform structure with a high degree of crystallinity with developed porosity, and are a promising material for further research with a view to introduction into medical practice.
Keywords: fluorapatite, hydroxyapatite, bioceramics, hardening, titanium oxide, zirconium dioxide, calcium fluoride, composite materials, microhardness
