摘要：

By rapid quenching in a twin roller apparatus, glass was found to occur widely in the systems of Li2O with Al2O3, Ga2O3, Bi2O3 and in mixed systems. Examination of the resulting flakes by X-ray powder diffraction, differential thermal analysis, and capacitance data revealed the occurrence of glass, glass transitions, crystallization exotherms and the nature of some of the crystallization paths. The log ionic conductivity of the glasses was found to follow a linear relationship with the Li concentration. Evidence was observed for three new metastable crystalline phases, one in the Li2OAl2O3 system and two in the Li2OBi2O3 system. The latter system also showed evidence for the occurrence of two glasses at almost all compositions. © 1979.
