Thermodynamische Untersuchungen am System CoO.MgO
Abstract
A series of solid solutions Co xMg 1- xO was studied thermodynamically in the range from 1100 to 1300 K by means of solid state galvanic cells using oxygen-ion conductors. The activities of CoO in the solid solutions show positive deviations from Raoult's law. The solid solutions are interpreted to be regular within the limits of error. The values of the free enthalpy of mixing are approximately 20% more positive than in the case of ideality; data of the excess enthalpies therefore are slightly positive.
