Notes:
Carbonate apatite single crystals were grown under 50 MPa of argon gas using CaCO3 flux. The crystals obtained were hexagonal prismatic, 1 mm in length and 200 μm in diameter. Carbonate ions occupied both A(OH)-sites and B(PO4)-sites; A-sites were completely substituted by carbonate ions. The space group was determined using a four-circle diffractometer to be P〈inlineGraphic alt="inline image" href="urn:x-wiley:00027820:JACE746:JACE_746_mu1" location="equation/JACE_746_mu1.gif"/〉. From the angular dependence of polarized IR spectra for out-of-plane and in-plane bending vibrations of CO3 ions, it was indicated that the triangular plane of the CO3 ion was parallel to the c-axis for A-site substitution and perpendicular to the c-axis for B-site substitution.
