Abstract
Synthetic apatites were precipitated in the presence of magnesium and carbonate, at room temperature, and their maturation followed. A cryst allinity index for each sample was calculated from Fourier transform i nfrared (FTIR) spectra. It is shown that there is a synergetic effect between carbonate and magnesium in delaying the increase of the crysta llinity index with maturation. Deconvoluted FTIR spectra of these apat ites confirmed the presence of an extra band at 620 cm(-1). Its evolut ion is shown and its assignment discussed on the basis of comparison w ith deuterated samples.
