    Depending on the purpose, chromic anhydride is produced in grades A, B and C.

    It is widely used in mechanical engineering, metallurgical, chemical, petrochemical and other industries for:

    • production of high-purity metallic chromium, superhard materials, some catalysts for chromium plating, chromating and passivation processes (grade A).
    • production of electrolytic chromium, production of catalysts (grade B).
    • production casting as part of molding and core sands, for etching processes and other purposes (grade B).
