Iron Oxide Yellow 313

Iron oxide yellow have excellent exquisite, superb weatherability, fine dispersion, strong tuning power, stable performance, and is a green and environmentally no-toxic paint, has excellent lightfastness, good heat resistant and alkali resistant.
Good dispersion/hiding power is strong/strong tinting strength.

Iron oxide yellow pigment has a wide range of uses. It can be used as a pigment or colorant in all kinds of concrete prefabricated parts and building products. It can also be used in various architectural glass and ceramics. It also has certain applications in the magnetic material industry. .

 

1. Characteristics:
Iron oxide yellow is an inorganic substance with the chemical formula Fe2O3, which is a Lemony yellow to brown powder. The relative density is 2.44~3.60. Melting point 350 ~ 400 ℃. Insoluble in water, alcohol, soluble in acid. The powder is fine and it is a crystalline iron oxide hydrate. Due to the different production methods and operating conditions, the degree of hydration is different, and the crystal structure and physical properties are very different. Good tinting strength, hiding power, light resistance, acid resistance, alkali resistance and heat resistance.
