【Abstract】 The preparing process of micaceous iron oxide pigments was studied by the hydrothermal method from the
ferrous sulfate by produced in the production of titanium dioxide . XRD and SEM were used to analyze the product . The law
that the reactive medium ,hydrothermal temperature and reaction time influenced the crystallization and the characteristics
of product was obtained. HOwas used as oxidizing agent ,ammonia water was used as precipitate to born precursor 2 2
2 - () Fe OHand NaOH alkali liquid was used as reactive medium. The preparing process handled the question of SO,and 3 4
made the reactive medium be recycled.
