Abstract
Triangulation of the quaternary Ag-Cd-Sn-S system in the Ag2SnS3-SnS-Sn2S3-CdS part below Tâ¯=â¯600â¯K was performed 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. The forming reactions were performed by applying electrochemical cells (ECCs): (â) Câ¯|â¯Agâ¯|â¯Ag2GeS3 glassâ¯|â¯Ag2CdSn3S8, SnS, Sn2S3, CdSâ¯|â¯C (+) and (â) Câ¯|â¯Agâ¯|â¯Ag2GeS3 glassâ¯|â¯Ag2CdSnS4, SnS, Ag2CdSn3S8, CdSâ¯|â¯C (+), where C is graphite and Ag2GeS3 glass is the fast purely Ag+ ions conducting electrolyte. The linear dependencies of the EMF of the ECCs on temperature in the range Tâ¯=â¯(462-500)â¯K were used to calculate the standard thermodynamic values of the Ag2CdSn3S8 and Ag2CdSnS4 phases for the first time.
