Abstrakt

Phase equilibria and
thermodynamics in the Ag2SnS3–SnS–Sn2S3–FeS
system were investigated using differential thermal analysis, X-ray
diffraction, and EMF methods. Determined phase relations were used to express
the forming chemical reactions for compounds Ag2FeSn3S8
and Ag2FeSnS4. The forming chemical reactions were
performed 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. temperature
relations, experimental thermodynamic data of the quaternary phases Ag2FeSn3S8
and Ag2FeSnS4 were derived for the first time.
