Abstract
Manganese is usually present as a minor component in alloys designed for high temperature oxidation resistance, and promotes the formation of protective spinel layers. Although thermodynamic data on liquid Fe-Mn alloys are well established, 1 there is a lack of corresponding experimental information regarding Ni-Mn alloys. Available data on solid Ni-Mn alloys have been evaluated by Hultgren et al.1 A solid state emf cell, with yttria doped thoria as the electrolyte and a mixture of Cr + Cr203 as the reference electrode, is employed in this study for measurement of the activity of manganese in the Ni-Mn system at 1683 K, for 0.4 > Xun > 0.05. The liquid alloy is contained in an alumina crucible and saturated with MnA12+2,O4+3x. The cell can be represented as:
