Abstract

A modified technique was proposed for the liquid-phase synthesis of hydroxyapatite allowing one to increase the stoichiometry of the product (the ratio Ca/P = 1.64) in comparison with the standard technique (Ca/P = 1.31). A comparison of the basic physicochemical characteristics for the synthetic and biological hydroxyapatite on the surface of zirconium was carried out. Calcium phosphate biocompatible coatings were obtained on the surface of zirconium basing on the synthesized and biological hydroxyapatite.
