Using X-ray phase analysis, the calcium substitution with Nd and Dy in hydroxyapatite Са₁₀₋xLnx(РО₄)₆(ОН)₂-хОх at 1100°C has been established to take place up to x = 2.0 and 1.4, respectively. The IR spectroscopy has shown that along with the Ca²⁺ +ОH⁻ → Ln⁺³ + O²⁻ substitution, the 2ОH⁻ O²⁻ + □ on...
