| Abstract | ||||
| The composition effect on FTIR spectra, D. C. electrical conductivity, density and molar volume have been carried out for five glasses (G1 to G5) of (13 M2O or M’O) – 78 B2O3 – x Al2O3 – y Nacl system, where M is Li, Na or K and M’ is Ba; x = 9 and y = 0 for G1, while for G2, G3, G4 and G5: x = 3 and y = 6 mol %. FTIR spectra have been recorded in wavenumber range from 4000 cm-1 to 400 cm-1. Eight absorption bands were observed in the rgion from 400 – 1750 cm-1. The electrical conductivity yield activation energies for the investigated glasses. These activation energies as well as the density and the molar volume have been found to be in the fallowing order Li+ < Na+ < K. The molar volume, density and the activation energy for barium oxide seem to be constant whether Na Cl is present or not. | ||||
