| titleOfInvention | Process for treating chromium dioxide |
| abstract | Ferromagnetic chromium dioxode is normally produced using other chromium compounds as starting materials. In most reactions a Cr(VI) compound, such as chromium trioxide is used in some stage of the procedure. Following the conversion reaction there are inevitably small amounts of the original chromium (VI) ions in the form of salts or oxide compounds which are strongly adsorbed on or attached to the chromium dioxide in a manner which prevents them from being easily removed by normal washing techniques. These Cr(VI) ions, if left in the chromium dioxide can cause problems. These disadvantages have now been overcome by treating the impure chromium dioxide with a peroxide compound in a manner which causes the Cr(VI) ions to change their character and allow their removal from the chromium dioxide. |
