Characterization and mechanical performance of the Mg-stabilized beta-Ca-3(PO4)(2) prepared from mg-substituted Ca-deficient apatite

abstract

The preparation of Mg-stabilized beta-tricalcium phosphate (beta-TCP) was carried out by an aqueous precipitation method and the characterization of the powders was performed by powder X-ray diffraction, FT-IR spectra, Raman spectroscopy, and elemental analysis. The transformation of calcium-deficient apatite into beta-TCP has occurred in the range of 700 degrees-800 degrees C. The calculated values for lattice parameters confirm the stabilization role played by Mg. The thermal stability of the Mg-stabilized beta-TCP powders was evident until 1400 degrees C, thus broadening the sintering temperature range without transformation into the undesirable alpha-TCP. Accordingly, the mechanical properties of the Mg-stabilized beta-TCP were improved in comparison with those of pure beta-TCP.
