About Iron Oxide, Fe2O3 powder
Iron III oxide, haematite, and ferric oxideare inorganic compounds that have the molecular formula Fe2O3. It is one the three major forms of iron.

Fe oxide, iron triooxide have the same formula Fe2O3. This inorganic compound is one of the main iron oxides found naturally in the mineral magnetite. The unique magnetic properties of iron dioxide make it a great suspension for use in applications within biomedicine, agriculture, and the environment. It also has easy separation techniques. Pulsed iron oxide's advantage is its ability to be modified using a wide range of inorganic or organic compounds (such starch, polyelectrolyte, and non-ionic detergent), so it can be used for a wider variety of applications. Magnet iron oxide can also be used in medical applications.

The iron oxide compound has ferromagnetic qualities. Magnetic properties can be achieved when the compound is placed in an external magnet field. They can exhibit this characteristic when they are controlled in size and crystal structure. The magnetic properties of iron oxide and their ease-of-use separation have made them the focal point of medical diagnostics and magnetic resonance imaging. While the use of iron oxide on the large scale is important, its reactivity and the size distribution are also crucial. However, when the particles are smaller in the nano and micron scales they can spontaneously combust. Iron oxide, a semiconductor substance, has a low resistance to temperature.

Iron Oxide Fe2O3 powder performance:

It can be reddish-brown powder or iron oxide red. Odorless. Water, organic acids, and organic solvents insoluble. It is also soluble in organic acids. You can choose from two kinds: g (diamagnetic) or a (positive magnetic). Dry-produced products generally have a fineness below 1mm. They are stable to light, heat, and air. It is less sensitive to alkali and acid. Strong coloring power. Relative density of 5.12 5.24. A lower content means a lower relative density. Refractive Index 3.042. Refractive index 3.042.

It is simple. Iron Oxide Fe2O3 Powder produced?
Wet or dry preparations of Iron Oxide Fe2O can be done in one of two ways. Products made using wet processing have soft and fine crystals. These products are also easy to process as pigments. Products made from dry processes have larger crystals and harder particles that are ideal for magnet materials, polishing, and abrasive material.
1. Get Wet This method
You will need to quickly react some 5% ferrous sulfurate solution with some excess sodium hydroxide. (The alkali excess must be 0.040.08g/mL). Then you can pass the mixture in to the air at room temp to transform it into reddish-brown ferrichydride colloidal solution. As the carrier, take the crystal nucleus and use ferrous-sulfate to act as the medium. When there is metallic iron present at 7585 the ferrous Sulfate reacts and forms iron oxide.
2. Dry method
Iron reacts with Nitric acid to create ferrous nitrate. This is then cooled and crystallized. Then it is dried. Finally, the iron oxide product can be ground by washing with water. You can use iron oxide yellow as a raw material for red iron oxide. This is after it has been calcined at 600700.

Applicaciones Iron Oxide Fe2O3 Powder :
1. Iron industry
It is used as the primary feedstock in the steel and iron industries. Iron, steel and other alloys are produced.
2. Polishing
The fine ferric oxide powder known as "jeweler’s red", "red rouge", and simply "roi" is the name for it. It's used to polish metallic jewellery and lenses. It cuts faster than modern polishes such as cerium(IV), but it is still useful in optics fabrication, and jewelers for the exceptional finish that it can provide. Rouge slightly marries gold and makes it look better. The rouge can be sold in powder or paste form. It is also laced on polishing cloths and solid bars with a grease binder. Rouge is sometimes used in conjunction with other polishing agents, even though they are not made from iron oxide. The ultrasonic cleaning can be used to clean jewelry of any remaining rouge. To give razor edges to knives and straight razors or other sharpened tools, "stropping chemicals" can be applied to leather strops.
3. Iron oxide pigments
These two colours are used to make pigments.
Iron(III), oxide may also be used in pigments under the names of "Pigment Brown 6", 7", and 101. Some of these, like Pigment Red 101 or Pigment Brown 6, can be used as pigments. Pigment Red 101 and Pigment Brown 6 have been approved for cosmetics by the US Food and Drug Administration. In dental composites, titanium oxides and iron oxides both are used as pigments. Falu-red is made up of hematite, which is the most distinctive component in the Swedish paint.
4. Magnetic recording
Iron (III-Oxide) was the most widely used magnetic particle for all kinds of magnetic storage and record media. This included magnetic disks (for data retention) and magnetic tape (used to store data and audio). The use of iron(III) oxide in computer disks has been superseded with cobalt alloy. This allows for thin magnetic films that have a higher storage density.
5. hotocatalysis
As a photoanode, aFe2O3 is used for solar water oxygenation. The reaction requires high overpotential, which limits its effectiveness. The research has focused on improving water oxidation performance for Fe2O3 through nanostructuring, surface functionalityization or employing alternate crystal phase such as the b-Fe2O3.
6. Me dicine
Calamine lotion, which is used to relieve mild itching, is composed mainly of zinc oxide. This acts as an astringent. The active ingredient in the product, iron(III), works as an antipruritic. This is what gives the lotion its pink color.
