Abstract:

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. 3q2966-2973 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.
