ACTIVITY OF INDIUM IN LIQUID IN-BI-AG AND IN-BI-TE ALLOYS MEASURED BYEMF METHOD USING ZIRCONIA ELECTROLYTE

The activities of indium in liquid In-Bi-Ag and In-Bi-Te alloys have b een determined by the emf measurement using zirconia electrolyte at 89 6 similar to 1297 K and 816 similar to 1111 K for 15 and 18 compositio ns of the alloys, respectively. Combining the binary data of In-Bi and In-Ag alloys in In-Bi-Ag system, In-Bi and In-Te alloys in In-Bi-Te s ystem for this study, isoactivity curves at 1100 K and 1200 K. 900 K a nd 1000 K were obtained in the whole composition range, respectively. There seem no published data to be compared with.
