Members of the system Cr_2-xRh_xO₃(2≥x≥0) were prepared by thermal decomposition of the nitrates. Magnetic measurements indicate that the chromium-rich members are antiferromagnetic and the spin-only moment, extrapolated from the high-temperature portion of the susceptibility curves, corresponds to Cr(III). Reduction studies indicate that the rhodium was stabilized in the solid solution and that at elevated temperatures between 1100 and 1200°C the mixed oxides were reduced to either the elements or a rhodium-chromium alloy.
