It was shown that the direct liquid-N quenching technique gave rapid cooling rates and permitted greater LiI saturation values and higher conductivities. The properties were comparable to those obtained by using the roller quenching method. The conductivity of 0.0018S/cm at 25C, which was measured for LiI-0.36Li2S-0.24SiS2 (table 268), was one of the highest values then reported for a Li+-conducting sulfide glass, and exceeded that for Li+-conducting crystalline materials.
