چکیده انگلیسی
CrO2 requires non-ambient conditions to stabilize Cr in 4+ state. Usually it is prepared by the hydrothermal method which requires high pressure and super criticality of water. For more than a sesqui century there are no reports on the preparation CrO2 by a simple single step rapid synthesis method at ambient condition. The self ignition exothermic combustion reaction between CrO3 and acetone vapor cloud leads to ultra fast formation of CrO2 particles enroute Cr2O3 from CrO3 at ambient condition. The condition for commencement of self ignition and the reaction mechanism are discussed. The structural, morphological, electrical and magnetic studies of the formed CrO2 particles are also presented.
