Iron oxide yellow

YellowIron oxide yellow short, the aqueous iron oxid  from lemon yellow to brown powder. The relative density of 2.44 ~ 3.60. Melting point 350 ~ 400 ℃. Insoluble in water, alcohol, dissolved in acid. Fine powder is crystalline iron oxide hydrate. As production methods and

Operating conditions, the different degree of hydration, crystal structure and physical properties are very different. Color strength, opacity, light resistance, acid resistance, alkali resistance, heat resistance are good. Above 150 ℃ decomposition of crystalline water, into the red. Inhalation of dust can cause pneumoconiosis, empty

Maximum allowable concentration of gas 5mg/m2.
