Early research on Ag 3 AuSe 2 and Ag 3 AuTe 2 explored structural transitions at high temperatures using differential thermal analysis (DTA) and X-ray diffraction (XRD). Both compounds have similar melting points around 730 • C and undergo multiple phase transitions at elevated temperatures. Although synthesis of Ag 3 AuSe 2 and Ag 3 AuTe 2 have been reported, experimental data on the physical and chemical properties of the synthetic samples remain limited.
