    Abstract

    Dielectric constants were measured for phosphate and silica glass systems in the frequency region of 1 to 10 GHz using the resonance cavity method. Compositional dependence of dielectric constant and tangent loss were discussed. The effect of the cations on the e indicates that e increases in the order, R:Mg <Zn<Ca<Sr<Ba and thus depends upon the ionic radius. The effects of Mg and Zn cations on the refractive index and dielectric constant were different from those of Ba,Sr, and Ca cations, that is Mg2+ and Zn2+ have coordination numbers of about 4 and would partially play a role similar to a silica- network in phosphate glasses.
