Abstract
The article discusses the possibility of obtaining a hardened composite material with a structure of different porosity based on nanostructured hydroxyapatite synthesized by precipitation from solution. In this work, mechanochemical synthesis of composite materials based on hydroxyapatite was carried out in a vibrating mill with simultaneous mixing and grinding of initial components and property-modifying additives (Si, Al, Zr, SiO2, Al2O3, ZrO2, 10–20 wt.% each) followed by annealing in the temperature range 200 ℃–1000 ℃. The synthesized samples were certified using modern physico-chemical methods of analysis. The influence of the qualitative and quantitative composition of the composite on the sintering processes, porosity, strength characteristics, degree of dispersion and morphology of the studied samples was shown. The peculiarities of chemical interaction of hydroxyapatite with reinforcing additives during heat treatment, the effect on grain size, and changes in the properties and structure during annealing were revealed. The effect of the phase composition and the amount of introduced additives on the strength characteristics of the investigated samples was shown. The optimum amount of reinforcing additives providing the production of a dense and strong composite material was determined.
