Abstract

X-ray photoelectron spectroscopy (XPS) has been applied to the structural analysis of amorphous calcium phosphate (ACP) and for the purpose of comparison also to that of calcium phosphate glasses with compositions 35, 45 and 55 mol% CaO. In the case of the phosphate glasses, from the measurements a discrimination between bridging, non-bridging and double bonded oxygen atoms was possible. In this study, the short-range structure of ACP was discussed.
