Iron Oxide Fe3O4 Powder CAS 1317-61-9

About Iron Oxide Fe3O4 Powder
Iron oxide (II, III) Fe3O4 is a highly insoluble and thermally stable iron source suitable for glass, optical and ceramic applications. Oxide does not conduct electricity. However, certain oxides of perovskite structure have conductivity in the cathodes of solid oxide fuel cells and oxygen generation systems. They are compounds containing at least one oxygen anion and one metal cation. They are generally insoluble in aqueous solutions (water) and are very stable, making them useful for ceramic structures, as simple as the production of clay bowls for advanced electronic devices, and for lightweight structural components in aerospace and electrochemical applications such as fuels Batteries in which they exhibit ionic conductivity. Metal oxides are basic high-purity (99.999%) iron oxide (FeO) anhydrides, so they can react with acids and strong reducing agents in redox reactions. Iron oxide can also be made into particles, nuggets, powders, sputtering targets, tablets, and Nanopowders. In most cases, iron oxide is usually available immediately. High purity, submicron and Nanopowder forms can be considered. Provide other technical, research, and safety (MSDS) information.

Ferric oxide has ferromagnetism. If the radius of the formed particles is on the nanometer level, it is called ferromagnetic particles.

Technical Parameter of Iron Oxide Fe3O4 Powder：

How is Iron Oxide Fe3O4 Powder Produced?
Gas phase oxidation method:
The gas phase oxidation method oxidizes iron oxides in oxygen to produce ferric tetroxide at high temperatures. The reaction equation is:
3FeO(s) + O2(g) → Fe3O4(s)
Gas phase oxidation requires high-purity iron and oxygen as raw materials, while the reaction temperature and atmosphere must be controlled. This method has the advantages of high product purity and production efficiency, but it needs to use high-energy fuel or electricity, and the production cost is high.

Solid phase synthesis method:
The solid phase synthesis method is the solid state reaction of iron oxides or iron salts with other metal oxides or salts at high temperatures to produce ferric oxide. This method has the advantages of a simple process and low production cost, but the product purity is low and needs to be washed and refined several times.

Thermal decomposition method:
The thermal decomposition method uses ferrous nitrate or oxalate at high-temperature thermal decomposition to obtain ferric oxide. The reaction equation is:
2Fe(NO3)2(s) → Fe3O4(s) + 2NO2(g) or 2FeC2O4(s) → Fe3O4(s) + 2CO2(g)
The thermal decomposition method has advantages due to its simple manufacturing process and the highest purity of the product. Still, it must use high-purity ferrous nitrate or oxalate as raw materials, and the production cost is high.

Electrochemical method:
The electrochemical method uses iron as an electrode, the electrochemical reaction in the electrolyte solution to produce iron tetroxide. This method has the advantages of high product purity and production efficiency, but it needs to use special electrolytic equipment and power supply, and the production cost is high.

Chemical vapor deposition method:
Chemical vapor deposition is the chemical reaction of iron compounds with other metal compounds at high temperatures to produce ferric oxide. This method has the advantages of high product purity and adjustable film thickness, but it needs special equipment and technology, and the production cost is high.

Applications of Iron Oxide Fe3O4 Powder
Magnetic material:
Ferric oxide is a common magnetic material with high permeability and magnetic induction. It is widely used in electronics, telecommunications, medical and aerospace fields. For example, ferric oxide can be used in electronics to manufacture magnetic recording materials, electromagnets, transformers, etc. In medicine, ferric oxide can make magnets for magnetic resonance imaging (MRI) and magnetic drugs.

Catalyst:
Ferric oxide can be used as a catalyst for various chemical reactions. It can improve the rate and selectivity of the reaction but also can reduce the condition and cost of the reaction. For example, ferric oxide can be used for hydrogenation reactions, oxidation reactions, dehydrogenation reactions, etc.

FAQ of Iron Oxide Fe3O4 Powder：

Q: What is Fe3O4 called?
A: Fe3O4 is commonly known as magnetite or ferrous ferric oxide. It is a naturally occurring iron oxide mineral that is notable for its magnetic properties. Magnetite is widely used in various industrial applications, including as a raw material in the steel and iron industries, in magnetic recording media, and in medical applications due to its biocompatibility and magnetic responsiveness.

Q: Are Fe2O3 and Fe3O4 the same?
A: No, Fe2O3 and Fe3O4 are not the same. Fe2O3 is hematite, a red iron oxide, which is non-magnetic and commonly used in pigments and as a source of iron in metallurgy. Fe3O4 is magnetite, a black magnetic iron oxide, used in various applications due to its magnetic properties and chemical stability.

Q: Is Fe3O4 a mixed oxide?
A: Yes, Fe3O4 is a mixed oxide, containing both Fe(II) and Fe(III) ions. Its chemical formula can be written as FeO·Fe2O3, indicating the presence of ferrous (Fe2+) and ferric (Fe3+) ions in the compound. This mixed valence state gives magnetite its unique magnetic and chemical properties, making it valuable in various industrial and technological applications.
