Abstract: The article discusses the possibility of strengthening nanostructured hydroxyapatite (HAP) obtained by precipitation from a solution by introducing zirconium oxide and calcium fluoride. The influence of qualitative and quantitative composition on sintering processes and strength characteristics of investigated samples has been shown. It was found experimentally that the sample has the maximum strength characteristics and constant composition Ca10(PO4)6(OH)2 – 15%CaF2 – 5%ZrO2. The composite has a dense uniform structure with a high degree of crystallinity and is a promising material for further research in order to introduce it into medical practice.

Keywords: hydroxyapatite, composite biomaterials, microhardness
