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?
Iron tetroxide is produced by the Schikorr reaction. This reaction converts iron (II) hydroxide (Fe(OH)2) into iron oxide (II, III) (Fe3O4). Under anaerobic conditions, ferrous hydroxide (Fe(OH)2) oxidizes in water to form magnetite and molecular hydrogen. Schikorr 's reaction explains this process.
3Fe(OH)2→Fe3O4 + H2 + 2H2O
Ferrous Hydroxide Magnetite Hydrogen Water.
 
Applications of Iron Oxide Fe3O4 Powder
Triferric tetroxide, commonly known as iron oxide black, magnetite, and black iron oxide, can be used in many different fields, for example:
Iron (II, III) oxide is used as a black pigment also known as Mars Black.
It is used in the Haber process as a catalyst.
It is used in the water-gas shift reaction.
Fe3O4 magnetic Nanoparticles are used in MRI scanning as contrasts against it.
It protects the steel from rusting.
It is an ingredient in thermite which is used for cutting steel.

Performance of Iron Oxide Fe3O4 Powder：
Ferric oxide has ferromagnetism. If the radius of the formed particles is on the nanometer level, it is called ferromagnetic particles.
