Iron Oxide Properties

Performance of Iron Oxide Fe2O3 powder:

Iron oxide red to reddish brown powder. Odorless. Insoluble in water, organic acids and organic solvents. Soluble in inorganic acids. There are two types: α-type (positive magnetic) and γ-type (diamagnetic). The fineness of dry-produced products is generally below 1μm. Stable to light, heat and air. It is more stable to acid and alkali. Strong coloring power. The relative density is 5.12~5.24. The lower the content, the lower the relative density. Refractive index 3.042. Melting point is 1550℃, decomposes at about 1560℃.
