| titleOfInvention | Novel ferromagnetic chromium dioxide and rhodium dioxide material and its preparation |
| abstract | Process for making a novel ferromagnetic chromium dioxide and rhodium dioxide material in the form of a solid solution Cr1-xRhxO2 where x is a number between 0 and 0.5. It essentially comprises oxidation, under suitable conditions of temperature and pressure, of hydrated or anhydrous Cr2O3 or of a precursor of Cr2O3, in the presence of (1) an appropriate amount of a compound of rhodium III able to give RhO2 under reaction conditions and (2) of an oxidizing agent consisting of an oxygenated compound free from metallic cations other than chromium and having, under the reaction conditions, a partial oxygen pressure at least equal to that corresponding, under the same conditions of temperature and pressure, to the equilibria Cr2O3+1/2O2-><-2CrO2 and Rh2O3+1/2O2-><-2RhO2 as well as eventually (3) of dilution water and/or of at least an additional doping agent acting as buffer in the reaction medium and/or a conventional modifying agent. The invention is useful for the manufacture of a ferromagnetic material possessing improved magnetic characteristics. |
