Infrared spectra of metaphosphate glasses

The infrared transmission spectra of binary alkali or alkaline-earth metaphosphate glasses have been determined. The glass systems include Li2O.P2O5, Na2O.P2O5, K2O.P2O5, Rb2O.P2O5, CaO. P2O5, SrO. P2O5, BaO. P2O5 and the devitrified K2O.P2O5. Three sampling techniques, namely, the thin film, the KBr-pellet and the reflection have been compared by their infrared spectra in the wavelength 2 to 15 microns. The IR spectra with identical results. Studies have been made on the possible re-orientation of the structure of Na2O.P2O5 glass prepared by extended period of melting, blowing into films and drawing into fibers without change in glass structure. A zigzag chain model of the sodium metaphosphate glass is derived from the X-ray scattering studies by Milberg and Daly Jour. of Chemical Physics (U.S.A.) 3q:2966-2973 (July 1963). Using the Wilson FG-matrix technique, a group theoretical analysis of the model has been carried out, with close agreements between the predicted normal frequencies and observed frequencies.
