Abstract
An overview of possible anionic substitutions in the structure of hydroxyapatite for the mechanochemical method of synthesis is presented. It was revealed that single-phase nanocrystalline varieties of anion-substituted hydroxyapatite are formed during mechanochemical synthesis. A series of the samples of carbonate-, silicate-, aluminate-, zirconate- substituted hydroxyapatites with different concentrations of the substituent ion were obtained. It was established that additional high-temperature annealing leads to partial loss of the substituent ion, which results in the formation of impurity phases. Silicate-, aluminate-, and zirconate-containing hydroxyapatite species may be of interest as coatings of medical implants made of metal and zirconium-corundum ceramics.
