The present invention provides a method for producing sodium chromite (NaCrO2) that does not substantially contain hexavalent chromium and has a single phase as observed by X-ray diffraction by an industrially advantageous method using sodium dichromate (Na2Cr2O7). The present invention is a method for producing sodium chromite (NaCrO2), which is characterized by comprising burning a mixture, which is a mixture comprising sodium dichromate (Na2Cr2O7) and a carbon precursor capable of releasing carbon upon being subjected to the thermal decomposition by burning in a vacuum or inert gas atmosphere, in a vacuum or inert gas atmosphere. In the method, the temperature for the burning is preferably 700 to 1200˚C. |
