Quenched Li-containing multiple sulfate glasses

Abstract

Over one hundred quenched melts containing lithium, other alkali, and/or alkali earth or other divalent metal sulfates were examined by differential thermal analysis and powder X-ray diffraction. Glasses formed in many of these quenches, but pure glass generally was obtained only in ternary compositions and even then only in limited concentration ranges. Ionic conductivities ranged up to 10 −3 (Ω cm) −1. Systematic variations, of the Li concentration and of ionic sizes, for example, were investigated. No factors were found which could be clearly correlated with either the occurrence of glass or the magnitude of the ionic conductivity.
