| Summary: | The article discusses the possibility of obtaining a hardened composite material with a porous structure based on nanostructured hydroxyapatite (HAP) synthesized by precipitation from a solution. The new material by the mechanochemical synthesis of hydroxyapatite with aluminum, silicon, nickel, hafnium and titanium was obtained. The synthesized samples are certified using modern physical and chemical methods of analysis. 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 the Ca10(PO4)6(OH)2 – 15%CaF2-15%TiOx. system is the most promising for the development of biocomposites based on it. Composite materials of this composition have a dense uniform structure with a high degree of crystallinity, with developed porosity, and are a promising material for further research in order to introduce it into medical practice. The possibility of practical application of the obtained composite material as a component of a bioactive coating is evaluated. A patent application has been filed for the developed composite material. |
