Abstract
A method of preparation of solid solutions of Cr2O3 in nickel oxide has been described. The homogeneity of the solid solutions obtained was controlled by determining the nickel and chromium content polarographically in the course of the zone dissolution of the samples. The presence of chromium-nickel spinel was detected by the X-ray analysis. The limiting concentration of Cr2O3 in the solid solution in equilibrium with the spinel has been determined.
