ATR-IR spectra of (a) TCP- BG powders, bands corresponding to both BG and TCP phases are observed in the range 400–1200 cm−1 (b) after 1-week dissolution (c) after 4 weeks dissolution, and (d) after 8 weeks dissolution in SBF. The intensity of the hydroxycarbonate apatite layer increases with dissolution time and the amount of BG addition.
