The present invention is directed to a synthetic biomaterial compound based on stabilized calcium phosphates and more particularly to the molecular, structural and physical characterization of this compound. The compound comprises calcium, oxygen and phosphorous, wherein at least one of the elements is substituted with an element having an ionic radius of approximately 0.1 to 1.1 ANGSTROM . The knowledge of the specific molecular and chemical properties of the compound allows for the development of several uses of the compound in various bone-related clinical conditions. La présente invention concerne un composé de biomatériau synthétique à base de phosphates de calcium stabilisés et traite, plus particulièrement, la caractérisation moléculaire, structurelle et physique de ce composé. Celui-ci comprend du calcium, de l'oxygène et du phosphore. Au moins un de ces éléments est substitué par un élément présentant un rayon ionique d'environ 0,1 à 1,1 ANGSTROM . La connaissance des propriétés moculéculaires et chimiques spécifiques du composé permet de prévoir l'application de ce composé dans diverses conditions cliniques concernant les os.
