Abstract

Nonstoichiometric hydroxyapatites and carbonated hydroxyapatites are characterized by the thermally stimulated current technique. Since dielectric energy losses are cooperative, the compensation temperature has been chosen as fingerprint of the local order. Relaxation map analysis shows the existence of either monophasic or biphasic structures and analysis of polarization phenomena gives information on localization and interaction of defects with structural ions of the apatites
