Iron oxide yellow summarize

yellow iron oxide short, the aqueous iron oxide.
Physical and chemical properties (Physical Properties)
1, Fe2O3,% ≥ 86; 2, sieve residue (320 mesh),% ≤ 0.5; 3, water-soluble salt, ≤ 0.5%; 4, moisture, ≤ 1%; 5, oil absorption ,25-35%; 6 , PH value :3.5-7
Nature of the 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 the production method and the operating conditions, the degree of hydration of different 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, Air maximum allowable concentration 5mg/m2.
