Vibrational spectroscopic studies of a new class of oligophosphate glasses of biological interest: Part 2

Abstract

Abstract Examples of a class of glassy biomaterials with chemical composition similar to that of bone have been prepared by heating mixtures of calcium metaphosphate and hydroxylapatite. The Raman and infrared spectra of these materials are reported and discussed in relation to glass structure, which is of the linear polymeric type with chain length depending on the molar ratio R =[CaO]/[P 2 O 5 ]. The products of the thermal decomposition of hydroxylapatite have also been characterized spectroscopically.
