Abstract: In the prodn. of stabilised acicular ferromagnetic chromium dioxide by conversion of Cr (III) and Cr (VI) oxides at 200-600 deg. C and 100-700 bars in a high pressure reactor in the presence of water with addn. of modifying agent(s) and then surface redn. in an aq. suspension to form a Cr (III) cpd. on the surfaces, the novelty is that 0.1-5.0% (by wt. of chromium dioxide) of a mono- or poly-basic 2-6C hydroxy carboxylic acid.

Abstract: Ferromagnetic chromium dioxide is prepared by converting oxides of trivalent and hexavalent chromium under superatmospheric pressure and at elevated temperatures in the presence of water and with the addition of an antimony compound as a modifier and, if required, further additives in an amount of not more than 15% by weight, by a method in which the antimony compound is present in the form of a water-soluble salt whose anion contains one or more organic molecular moieties which are oxidized in concentrated chromic acid.
