The high-temperature solid-phase interaction of hydroxyapatite (HA) with magnesium, strontium, and zinc nitrates at the stage of annealing of ceramics was investigated. The phase composition and unit cell parameters of the obtained materials were studied for various metals introduced into the structure to different concentrations. The introduction of Mg led to partial decomposition of HA to tricalcium phosphate and tetracalcium phosphate, the addition of Sr caused partial formation of tetracalcium phosphate from HA, and the doping with Zn gave rise to single-phase HAs.
The synthesis and investigation of the materials in this work were supported by the Russian Science Foundation (project no. 16–13–00123).
