%X Reduction of potassium chromate and potassium dichromate to chromic oxide hydrate under hydrothermal conditions using sucrose as the reducing agent was investigated. The effects of the stoichiometric mole ratio of sucrose to chromate or dichromate salts (Rm), the isothermal temperature (Tiso) and time (tiso) on the conversion of Cr6+ to Cr3+ were also studied in detail. By using the orthogonal experiment L9(34), the order of the above affecting factors was obtained: tiso
