In the world of pigments, titanium dioxide stands tall as a favorite material for its ability to provide brilliant whiteness and exceptional opacity. Its refractive index is high, making it ideal for achieving that pure, lustrous look in paints and coatings. But its capabilities don’t end there; titanium dioxide is also prized for its stability and resistance to discoloration, ensuring longevity in artistic creations and protective layers.

The raw material used in this method is FeSO4. In order to maintain the Fe3 + concentration in the reaction medium in a specific range, reducing agent iron sheet is added in the reaction process. Iron yellow crystal seed was added and air was introduced to synthesize iron yellow under certain pH conditions. The method mainly includes two steps: (1) firstly, FeSO4 · 7H2O is used as raw material, NaOH or NH3 · H2O is used as precipitant or pH regulator, and air is used as oxidant to prepare crystal seed; (2) Iron yellow is produced by two-step oxidation with crystal seed, FeSO4, iron sheet and air.
