Introduction

The investigation of the Cu-In-S ternary system is related mainly to the studies of the CuInS₂ ternary compound which has semiconductor properties and a big practical importance (Table 1). The compound CuIn₃S₅ [1972Gan, 1974Gus] is probably metastable because it does not appear in subsequent Cu₂S-In₂S₃ diagrams. The melting point of CuInS₂ equals 1090°C [1988Aks, 1980Bin, 1983Bod, 1984Bod, 1985Mec, 1991Fea], 1080 ± 10°C [1990Rig], 1089 ± 2°C [1981Kue, 1984Kue], 1093 ± 3°C [1998Fie] and 1101°C [1991Mat]. The melting point from [1982Thi, 1983Thi...
