Here, NaOH or NH3 · H2O is used as a precipitant or pH regulator to react with FeSO4 to form ferrous hydroxide precipitation; Air is used as oxidant; The iron sheet reacts with sulfuric acid produced during the oxidative hydrolysis of FeSO4 to provide ferrous ions required in the reaction system and maintain the pH value of the solution. The alkali consumption of acid method is less and the particles are easy to wash. The relative rates of seed preparation and crystal growth determine the particle size, particle size distribution and particle morphology of iron yellow particles.

Does not work with hydrogen sulfide and alkaline solutions. It is easy to decompose in the presence of acid to produce hydrogen sulfide gas. It is easily oxidized in the air and deteriorates after moisture. Whiteness and hiding power are strong.
