用抽真空石英管在干体系中对Ａｇ２Ｓ－Ｔｌ２Ｓ假二元系在２５０℃下变温切面相平衡进行了实验研究。Ａｇ２Ｓ－Ｔｌ２Ｓ假二元系在２５０℃存在三个三元合成相，它们分别为ＴｌＡｇＳ、Ａｇ２９Ｔｌ１１Ｓ２０和Ａｇ１７Ｔｌ３Ｓ１０，后两个相是该实验首次合成
The phase equilibrium of Ag2S-Tl2S pseudo binary system at 250 ℃ was studied by means of vacuum quartz tube in a dry system. Ag2S-Tl2S pseudo-binary system at 250 ℃ there are three ternary synthetic phase, they were TlAgS, Ag29Tl11S20 and Ag17Tl3S10, the latter two phases of the experiment for the first time synthesis
