High Purity Iron Oxide Fe2O3 Powder CAS 1309-37-1,99.9% |

About iron oxide Fe2O3 Powder :
Haematite and Ferric oxide are inorganic compounds with the formula Fe2O3. It is the main oxidation of iron. Other forms are Iron oxide (II), or natural magnetite iron (II,III).

Fe dioxide and iron trioxide are inorganic compounds that have the formula Fe2O3. They are one of the main oxides found in magnetite, a mineral. Iron Oxide can be used in suspensions and solutions in biomedicine and agriculture. It has easy separation methods and unique super-magnetic properties. powdered ferrous oxide has the advantage that it is easily modified by adding a variety inorganic and/or organic compounds, such as starch or non-ionic detergents.

iron oxide is an iron oxide compound that has ferromagnetic qualities. If the compound is placed in a field of external magnetism, it becomes magnetic. The magnetic property can be obtained when the size and crystal structure are controlled. The low toxicity of iron oxide fine particle, their magnetic properties, and the ease with which they can be separated in magnetic resonance imaging and medical diagnosis have made them a popular choice. Iron oxide’s reactivity and application on a large scale are important factors. However, iron oxide in micron or nano sizes can spontaneously burn. Iron oxide, as a semiconductor, has a negative resistance to temperature.

What is Iron Oxide Fe2O3 Powder produced?
Iron Oxide Fe2O3 is prepared by both dry and wet methods. Wet-processed products are made of fine crystals and soft particles. They are easy to mill, and can be used as pigments. Dry-process products contain large crystals with hard particles. They are used for magnetic materials and polishing.
1. Wet It is a good way to get started.
Then, pass the ferric hydroxide colloidal solutions in the room air to turn them into a reddish brown color. This will be the nucleus for the deposited iron oxide. The crystal nucleus is used as the carrier. Ferrous sulfate is the medium. Pass in the atmosphere. The ferrous-sulfate solution, when in contact with metallic iron at 7585°C, reacts with oxygen to produce iron oxide, which deposits onto the crystal nucleus.
2. Dry method
After nitric acid reacts to iron, ferrous Nitrate is formed. This is dehydrated, dried, ground, and then calcined for 8-10hrs at 600-700degC. It’s then dried, washed, and pulverized. Iron oxide yellow is also a raw material that can be used for red iron after calcination between 600700.

Applications Iron Oxide Fe2O3 Powder :
1. Iron industry
The steel and iron industries use iron(III oxide) as a feedstock. The production of steel, iron and various alloys.
2. Polishing
A fine powder of ferric dioxide is called “jeweler’s red”, “red rouge”, and simply rouge. It was historically used as a cosmetic and to polish metallic jewelry and lenses. It cuts slower than some modern polishes such as cerium (IV) oxide but is still widely used by jewelers for its superior finish. When used to polish gold, rouge leaves a slight stain on the metal, which adds to the final appearance. It is available in powder form, paste form, on cloths for polishing, and as solid bars (with wax or grease as the binder). Many other polishing agents are called rouge, even if they do not contain any iron oxide. Jewelers can remove residual rouge from jewelry using ultrasonic cleaning. “Stropping compounds” can be applied to leather strops to help sharpen knives, straight razors or any other edged instrument.
3. Iron oxide pigments
The pigments are two colors of the iron(III oxide) hydrate at different phases (a = yellow, b= red) that can be obtained.
Iron(III), also known as iron oxide, can be used to make pigments. These include “Pigment Brown 6”, “Pigment Brown 7”, and “Pigment Red 101”. Some of these pigments, like Pigment Brown 6, are approved by the US Food and Drug Administration (FDA) for use in cosmetics. Pigment Red 101 and Pigment Brown 6 are approved for use as cosmetics by the US Food and Drug Administration. As well as titanium oxides, iron oxides can be used in dental composites. Hematite, the main component of Falu Red paint in Sweden, is characteristic.
4. Magnetic recording
Iron(III)oxide was the most popular magnetic particle used for all types of magnetic recording and storage media. These included magnetic disks, which are used to store data. Magnetic tape is also commonly used for recording audio and videos as well as storing data. The cobalt-alloy was used to replace it as a magnetic material in computer disks. This allowed for thinner magnetic films that had a higher storage density.
5. Photocatalysis
Researchers have studied a-Fe2O3 for its potential as a photoanode in solar water oxidation. The short diffusion distance (2-4nm) and rapid recombination of the photo-excited carriers limits its effectiveness. A large overpotential is required to drive this reaction. The research has focused on improving water oxidation performances of Fe2O3 through nanostructuring, functionalization or the use of alternate crystal phases, such as bFe2O3.
6. It is a good idea to use a different language. dicine
Calamine, a lotion used to relieve mild itching, is composed primarily of a combination zinc oxide and iron(III) oxychloride, an active ingredient that acts as antipruritic. Iron(III), which is red, is also responsible for most of the pink colour in the lotion.
