In recent years, experts have made use of Na2CO3 part instead of the conventional NaOH solution to precipitate ferrous sulfate and air oxidation to prepare seed crystals. By adding a small amount of Zn2 + salt as crystal nucleus regulator, Change its crystal nucleus morphology, to achieve low water absorption, high density characteristics. So that the oxidation of iron oxide into a low water absorption of heavy yellow oxide yellow pigment preparation process.
