Sammanfattning

Phase equilibria andthermodynamics in the Ag2SnS3–SnS–Sn2S3–FeSsystem were investigated using differential thermal analysis, X-raydiffraction, and EMF methods. Determined phase relations were used to expressthe forming chemical reactions for compounds Ag2FeSn3S8and Ag2FeSnS4. The forming chemical reactions wereperformed by applying electrochemical cells of the types:(–) C | Ag | Ag3GeS3I glass |Ag2FeSn3S8, SnS, Sn2S3,FeS | C (+) and (–) C | Ag | Ag3GeS3I glass |Ag2FeSnS4, SnS, Ag2FeSn3S8,FeS | C (+). Based on the measured EMF vs. temperaturerelations, experimental thermodynamic data of the quaternary phases Ag2FeSn3S8and Ag2FeSnS4 were derived for the first time.
