GeS2-Ga2S3-AgI system has a relatively narrow glass-forming region which extends from the GeS2-rich apex down to the sample containing 40% GeS2. Bulk glasses can be obtained when the content of Agl is less than 33%.

• GeS_2-Ga_2S_3-AgI系统玻璃成玻区较窄，其边界从GeS_2顶点延伸至含GeS_240%25的组成，当AgI含量小于33%25时可以得到稳定的块状玻璃。
