Introduction

A ternary phase AgAsTe₂ with semiconducting properties was reported and found to melt at 325°C [58Wer]. This compound could not be confirmed by [91Oll]. However, two other ternary phases, AgAs₃Te₅ and Ag₁₁AsTe₇ were reported, whereas a solid solubility between the latter and Ag₇Te₄ may exist [91Oll]. The isopleth Ag₂Te-As was found to be pseudobinary [76Gat, 78Gat] by thermal, X-ray and metallographic methods. Another pseudobinary section, Ag₂Te-As₂Te₃ was determined using X-ray diffraction [91Oll...
