Abstract
31NMR spectra of several inorganic phosphates have been examined both in the crystalline and the glassy states. The parameter (Zeff/r)q clearly demarcates ortho-, pyro- and meta-phosphates in terms of the 31P chemical shifts. Based on such a diagram, inorganic phosphate glasses are found to consist essentially of metaphosphate units. NMR resonance of the glasses are generally much broader than those of crystalline phosphates.
