Activity Measurements of Solid Ni-In Alloys by EMF Method with Zirconia Solid Electrolyte

摘要

The EMF of galvanic cells with stabilized zirconia solid electrolyte was measured to determine the activity of indium in solid Ni-In alloys in the temperature range of 970-1170 K and composition range of 5-55 mol% In.Activity of indium increases sharply in the zeta phase and Ni_(13)In_9 phase.The activity values are compared with literature data.
