✦ Synopsis
The {xMnO + (1x)NiO} solid solutions were studied thermodynamically in the temperature range from 973 K to 1173 K by solid-state galvanic cells containing b0-alumina electrolytes conducting manganese(II) and nickel(II) ions, respectively. The experimental procedure allowed us to determine the NiO and MnO activities directly from the e.m.f. measurements. The solutions exhibited positive deviation from ideal behaviour, but they could be regarded as regular solutions.
