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.

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.
Pigments and Coatings:
Ferric oxide can be important in pigments and coatings for producing high-grade coatings and pigment products. It can improve the whiteness and hiding power of the product and also control the product's drying speed and coating effect. In addition, ferric oxide can also be used as a phosphor, optical film, and other optical material applications.
Medical field:
In medicine, ferric oxide has antibacterial, anti-inflammatory, and anti-tumor biological effects. It prepares drug carriers, drug storage agents, and biomedical materials. For example, ferric oxide can be used as a drug carrier for drug delivery and treatment. It can also be used as a biomedical material for the manufacture of artificial organs.
Environmental protection:
Ferric oxide also has some applications in the field of environmental protection. It can be used as an automobile exhaust purifier and catalyst to reduce the emission of harmful substances in automobile exhaust. In addition, ferric oxide can also be used as a water treatment agent to remove harmful substances and odors from water.
