摘要：The glass forming regions of GeS2-Ga2S3-KX (X=Cl, Br, I) system glasses were determined and homogeneous glasses it-ere prepared. The maximum content in KI was 34 mol%. Their highest glass transition temperature (Td was 286 degreesC and optical transmission was from 0.45 to 11.5 mum. The transparent region of these glasses shifted towards shorter wavelengths after the addition of KX. The conductivity of these glasses was from 10(-11) to 10(-9)Scm(-1) at 23 degreesC. The chemical durability of these glasses was sufficiently good for applications. These glasses are of interest as potential mid-infrared and waveguide materials.
