In the present work, the formation kinetics of hydroxyapatite Ca10(PO4)6(OH)2 during ball milling of mixtures of calcium phosphates with Calcium oxide (cas 1305-78-8) or calcium hydroxide was studied. The conversion degrees of reaction mixtures containing calcium dihydrogenphosphate/dicalcium phosphate/tricalcium phosphate/calcium pyrophosphate and calcium oxide/calcium hydroxide were determined for different milling times. The formation kinetic data were analyzed together with the Gibbs free energies of the corresponding reactions. It was found that the kinetic factors dominate at the initial formation stage of hydroxyapatite due to the acid-base interactions during the “soft” mechanochemical synthesis. A technologically attractive synthesis route of Ca10(PO4)6(OH)2 was suggested based on the “soft” mechanochemical synthesis via reactions between СаНРО4 and СаО or Са(ОН)2.
