Sammanfattning
Triangulation of the quaternary Ag–Cd–Sn–S system in the Ag2SnS3–SnS–Sn2S3–CdSpart below T = 600 K wasperformed using X-ray diffraction method. The spatial position of the determined four-phase regions regarding the figurative point of silver was used to write forming chemical reactions. Theforming reactions were performed by applying electrochemical cells (ECCs):(–) C | Ag | Ag2GeS3 glass | Ag2CdSn3S8,SnS, Sn2S3, CdS | C (+)and (–) C | Ag | Ag2GeS3 glass | Ag2CdSnS4, SnS, Ag2CdSn3S8,CdS | C (+), where C is graphite andAg2GeS3 glass is the fast purely Ag+ ionsconducting electrolyte. The linear dependencies of the EMF of the ECCs ontemperature in the range T = (462–500) Kwere used to calculate the standard thermodynamic values of the Ag2CdSn3S8 and Ag2CdSnS4phases for the first time.
