摘要：

The glass formation regions are determined in the Ga2S3-GeS2-MCl (M = Li, Na, K, Cs, Ag, T1) and GaI3-NaCl systems. It is noted that the formation of complex structural units such as MGaS3/2Cl is favourable for increasing the glass-forming regions. Temperature dependencies of the electric conductivity of 60 samples in the system Ga2S3-GeS2-MCl were measured. All of these glasses have cation conductivity. Activation energy of conductivity for all investigated systems is a linear function on the cubic root of the atomic fraction of cations. These results correspond to the simple model of cation conductivity. (C) 1999 Elsevier Science B.V. All rights reserved.
