    • Abstract

       

      Glass formation region was determined for the B2O3-Li2O-Li3PO4 system. Under the present experimental conditions, binary lithium borate glasses could be formed containing a maximum of 27 mol% Li2O. However, this could be increased to 36 mol% in the ternary system. Electrical conductivity was measured at temperatures ranging from room temperature to 350°C. The temperature dependence of the electrical conductivity of these glasses follows Arrhenius equation. The conductivity increased with increasingly alkali content. Maximum conductivity of the order of 10−4 ohm−1 cm−1 was obtained with the glass containing about 36 mol% Li2O at 250°C. Activation energy for conduction also varied with total Li2O content.
