Abstract A structural, chemical and thermal investigation has been carried out on apatites submitted to cyclic pH fluctuation in the presence of fluoride, chloride and carbonate ions. Unlike fluoride, chloride is not appreciably incorporated into the apatite structure under cyclic pH fluctuation. However, the presence in solution of one of these ions inhibits carbonate substitution for phosphate groups in the apatite structure. The results reveal that grain growth during sintering is similar for the different samples, while slight differences in some technological properties (contraction during firing, softening point, etc) of sintered apatites have been detected.
