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℃.

Applications of Iron Oxide Fe2O3 Powder:
1. Iron industry
The overwhelming application of iron(III) oxide is as the feedstock of the steel and iron industries, e.g. the production of iron, steel, and many alloys.
2. Polishing
A very fine powder of ferric oxide is known as "jeweler's rouge", "red rouge", or simply rouge. It is used to put the final polish on metallic jewelry and lenses, and historically as a cosmetic. Rouge cuts more slowly than some modern polishes, such as cerium(IV) oxide, but is still used in optics fabrication and by jewelers, for the superior finish it can produce. When polishing gold, the rouge slightly stains the gold, which contributes to the appearance of the finished piece. Rouge is sold as a powder, paste, laced on polishing cloths, or solid bar (with a wax or grease binder). Other polishing compounds are also often called "rouge", even when they do not contain iron oxide. Jewelers remove the residual rouge on jewelry by use of ultrasonic cleaning. Products sold as "stropping compounds" are often applied to a leather strop to assist in getting a razor edge on knives, straight razors, or any other edged tool.
3. Pigment
Two different colors at different hydrate phases (α = red, β = yellow) of iron(III) oxide hydrate; they are useful as pigments.
4. Magnetic recording
Iron(III) oxide was the most common magnetic particle used in all types of magnetic storage and recording media, including magnetic disks (for data storage) and magnetic tape (used in audio and video recording as well as data storage). Its use in computer disks was superseded by cobalt alloy, enabling thinner magnetic films with higher storage density.
5. Photocatalysis
α-Fe2O3 has been studied as a photoanode for solar water oxidation. However, its efficacy is limited by a short diffusion length (2-4 nm) of photo-excited charge carriers and subsequent fast recombination, requiring a large overpotential to drive the reaction. Research has been focused on improving the water oxidation performance of Fe2O3 using nanostructuring, surface functionalization, or by employing alternate crystal phases such as β-Fe2O3.
