G. Rog et al., DETERMINATION OF THE ACTIVITIES IN (XCAO-X)NIO) BY SOLID-ELECTROLYTE GALVANIC CELLS IN THE TEMPERATURE-RANGE 1123 K TO 1313 K((1), Journal of Chemical Thermodynamics, 30(1), 1998, pp. 43-47
The activities of CaO and NiO in {xCaO + (1 - x)NiO} have been determi
ned in the temperature range 1123K to 1313K by the solid-electrolyte g
alvanic cell technique. The solubility limits of CaO in NiO and of NiO
in CaO have been estimated. The solutions exhibit strong positive dev
iations from ideal behaviour. (C) 1998 Academic Press Limited.
