Determination of the activities in {xCaO+(1-x)NiO} by solid-electrolyte galvanic cells in the temperature range 1123 K to 1313 K
The activities of CaO and NiO in {xCaO + (1 - x)NiO} have been determined in the temperature range 1123K to 1313K by the solid-electrolyte galvanic cell technique. The solubility limits of CaO in NiO and of NiO in CaO have been estimated. The solutions exhibit strong positive deviations from ideal behaviour.
