Ferroferricoxide is an inorganic compound with the chemical formula Fe3O4. Magnetic black crystals are also made of ferroferric dioxide.

Iron oxide


Fe3O4 powder Properties

Mixed valence iron oxide, the black Fe3O4 Powder is made. It has an melting point of 1597degC as well as a density at 5.18g/cm3. It is insoluble when it comes in contact with water, but it dissolves in acids. It is found as magnetite at room temperature in the natural form Fe3O4. It exhibits strong submagnetism, high conductivity.

Ferrocorric oxide will be produced by the combustion of iron wires in oxygen. Comparing Gibbs’ free energy from iron oxide to the mole standard, it becomes apparent that Fe3O4 exhibits the highest thermodynamic stability. Therefore, the product is Fe3O4.

Fe3O4 exhibits anti-corrosion properties. To bluish steel parts, also known as baking or blue-burning (or blue-burning), you use the alkaline-oxidizing solution’s oxidation effects to make a Fe3O4 coating on steel surfaces. It is useful to enhance corrosion resistance, aesthetics and gloss.

Fe3O4 powder Applications

In many industries, magnetic iron oxide is widely employed.

The most common type of magnetic material, ferroferric dioxide is.

For audio tapes and telecommunications equipment, pure ferroferric Oxide is specially made.

The raw material for iron-smelting is Fe3O4.

For primer and topcoat use Fe3O4 Powder

The main raw material to produce iron catalyst (a form of catalyst) is ferric oxide.

Fe3O4 can be used as an abrasive because of its hardness. It is widely used for automobile braking applications, like brake pads and shoes.

In the area of domestic welding, ferroferric dioxide has been recognised. The production of weld rods and wires are still in their infancy and there is a lot of potential.

Because of its specific gravity high and strong magnetic properties, Fe3O4 is a good choice for sewage treatment.

Also, ferroferric dioxide can be used to polish and as a pigment.

To prevent the steel from corroding, we can also make use of chemical reactions like the use of sodium Nitrite. This is often called “baked bleu” and blackened.

For special electrodes, Fe3O4 powder can be used.
