ResumoSuperionic glasses were prepared in the systems (100 − x) (0.6Li2S · 0.4SiS2) · zLixMOy (LixMOy = Li4SiO4, Li2SO4) by twin-roller rapid quenching. Glass transition temperatures (Tg) and crystallization temperatures (Tc) were determined for the glasses. The difference between Tg and Tc, which was one of the measures of glass stability against crystallization, was maxmized at the composition with 5 mol% Li4SiO4. The conductivity at 25 °C (σ25) was as high as 10−3 Scm−1 for the glass with 5 mol% Li4SiO4. The doping of Li2SO4, however, did not improve the glass stability against crystallization nor σ25
