Abstract

The reaction CrO3 + 2NH4X → CrO2 + 2 NH3 + H2O + X2 (X = Br, I), which occurs quantitatively at 120-150 ° C, provides a convenient method for the synthesis of CrO2; unlike conventional methods, the method reported here does not require the use of high pressure for the synthesis of this technologically important material.
