Study of the influence of anionic substitution in hydroxyapatite structure and properties of ceramics on it based

Abstract

The article discusses the possibility of strengthening stoichiometric hydroxyapatite obtained by precipitation from the solution by partial substitution of phosphate groups with silicate ions. Such characteristics of samples as phase composition, morphology, particle size distribution, specific surface area have been studied. It was established that the degree of substitution affects the mechanical properties of synthesized powders and ceramics after annealing.
