It has been shown that the proposed solid state synthesis technique has advantages over the most commonly used coprecipitation methodology, by avoiding the undesirable polymerization of the VO43- ion in an aqueous medium. The formation of strontium vanadateapatite occurs at 600 ° C as a monophasic sample. According to X-ray diffraction, the substitution of strontium for calcium in the structure of apatite vanadate containing gallium was achieved. The intercalated gallium atoms produce no structural distortion or alteration of the hydroxyapatite matrix. The qualitative X-ray mappings acquired from the same area of the sample provides images of homogeneous elemental distribution in the composite, thus confirming absence of compositional variations.The characteristics of the new material containing simultaneously three bioactive components are compatible with the natural human hydroxyapatite. The results obtained open the possibilities of introducing this composite into orthopedic practice.
