Iron oxide Fe3O4 has a wide range of uses

Overview of iron oxide Fe3O4

Ferroferric oxide is an inorganic substance with a chemical formula of Fe3O4. It is a magnetic black crystal, so it is also called magnetic iron oxide. It cannot be regarded as "ferrous ferrite" [Fe(FeO2)2], nor can it be regarded as a mixture of ferrous oxide (FeO) and iron oxide (Fe2O3), but it can be regarded as suboxide A compound composed of iron and iron oxide (FeO·Fe2O3). This substance is insoluble in water, alkali solutions, ethanol, ether and other organic solvents. The natural ferroferric oxide is insoluble in acid solution and is easily oxidized to iron oxide (Fe2O3) in the air in a humid state. Usually used as a pigment and polishing agent, it can also be used to make audio tapes and telecommunications equipment.

Three oxides of iron: ferrous oxide (FeO), iron oxide (Fe2O3), and ferric oxide (Fe3O4).

Ferric oxide is the only iron compound that can be magnetized in the middle school stage. Fe2+ and Fe3+ are contained in ferroferric oxide. X-ray diffraction experiments show that ferroferric oxide has a trans-spinel structure, and there is never a ferrite ion FeO22- in the crystal. Ferroferric oxide, the natural mineral type is magnetite. Iron has two valences in ferroferric oxide. It has a trans-spinel structure, and the oxygen is the most densely packed cube. In addition, Fe3O4 is also a conductor. Because Fe2+ and Fe3+ are basically disorderly arranged at the octahedral position in magnetite, electrons can quickly transfer between the two oxidation states of iron, so Fe3O4 Iron solids have excellent electrical conductivity. Fe3O4 can be regarded as FeO·Fe2O3. This way of writing better shows that Fe3O4 contains Fe(Ⅱ) and Fe(Ⅲ). 

Application of iron oxide Fe3O4

Ferroferric oxide Fe3O4 is a commonly used magnetic material.

Specially made pure ferroferric oxide is used as raw material for audio tapes and telecommunications equipment.

Natural magnetite is the raw material for iron smelting.

Used to make primers and topcoats.

Ferric oxide Fe3O4 is the main raw material for the production of iron catalyst (a kind of catalyst).

It is very hard and can be used as abrasive. It has been widely used in the field of automobile braking, such as: brake pads, brake shoes, etc.

Ferroferric oxide Fe3O4 has been recognized in the field of domestic welding materials, and the production of welding rods and wires is still in its infancy, and the market prospect is very broad.

Fe3O4 shows good performance in sewage treatment due to its high specific gravity and strong magnetism.

Ferroferric oxide  Fe3O4 can also be used as a pigment and polishing agent.

We can also use certain chemical reactions, such as the use of sodium nitrite, etc., to form a dense layer of ferroferric oxide on the surface of steel to prevent or slow down the corrosion of steel, such as the bluing of firearms, saw blades, etc. Blackened. Commonly known as "baked blue".

Fe3O4 can also make special electrodes.
