Abstract: 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 physico-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 system Ca10(PO4)6(OH)2 – Ti is the most promising for the development of biocomposites based on it. Composite materials of this composition with the content of the doping component (10-20 wt.%), have a dense uniform structure with a high degree of crystallinity, with developed porosity, are a promising material for further research in order to introduce it into medical practice. A patent application has been filed for the developed composite material.
