AgCu 1 − x Fe x S compounds were synthesized by partial Cu → Fe replacement in the AgCuS crystal at a concentration range of 0 ≤ x ≤ 0.03. In the differential thermal analysis spectrum obtained at a temperature range of 300 K ≤ T ≤ 1300 K, endoeffect corresponding to the structural phase transition in the AgCuS compound was observed at the temperature T = 938 K. It has been determined that this result is also observed in the AgCu 0. 9 9 Fe 0. 0 1 S compound obtained by partial replacement of Cu atoms by Fe atoms. However, in the compound of AgCu 0. 9 7 Fe 0. 0 3 S this effect was observed at higher temperatures. The thermal capacities and enthalpies of phase transitions were calculated for the given compounds. [ABSTRACT FROM AUTHOR]
