analysis and evidencing formation of the calcium phosphate silicate. The FTIR-ATR
spectrum recorded for the sample AsP after contact with SBF displayed peaks characteristic
of crystalline phosphate at 600 and 560 cm -1 , and carbonate hydroxyapatite, at 1451, 1408,
and 874 cm -1 [72]. This suggests that these materials can be used for bioapplications.
