    Abstract

    Na-incorporated β-tricalcium phosphate (β-TCP) was synthesized via the solid-state reaction method and a substitution mechanism for Na ions in the synthesized materials has been investigated by X-ray absorption near-edge structure (XANES) analysis. In addition, total electronic energy calculations within density functional theory were also carried out to obtain the most energetically favorable substitution site for Na ions in β-TCP. Both the spectroscopic and computational analysis indicate that substituted Na ions are likely to occupy Ca(4) site in β-TCP.
