Know more about the Magnetite Black Iron Oxide - Fe3O4

What is Iron (II, III) oxide Fe3O4 powder?
Iron (II, III) oxide powder, magnetic iron oxide (Fe3O4), chemical formula Fe3O4, is a compound composed of iron and oxygen, known for its unique magnetic properties and black appearance. In nature, it exists primarily in the form of magnetite, one of the most common iron-bearing minerals in the earth's crust. Tetraferric oxide powder, on the other hand, is a finely milled form that gives the material a higher specific surface area, which results in superior performance in many technological and industrial applications. Its powdered form not only facilitates mixing with other substances, but also improves dispersibility and reactivity, and is widely used in a variety of applications, including catalysts, magnetic recording media, biomedicine, and environmental remediation.
Characteristics of Iron (II, III) oxide Fe3O4
The distinctive features of Iron (II, III) oxide are its magnetic properties and unique crystal structure. As a typical magnetic material, it exhibits soft magnetic properties at room temperature, which means that it can be strongly attracted by an applied magnetic field and retains a partially magnetized state after the field is removed. In addition, the crystal structure of Iron (II, III) oxide is spinel-type, in which iron atoms exist in both Fe²⁺ and Fe³⁺ valence states, forming a complex oxide structure, which confers special properties in terms of electron transport and magnetism.
Physical Properties of Iron (II, III) oxide Fe3O4
The physical properties of Iron (II, III) oxide include:
Color and form: a black or dark brown powder or crystal.

Magnetism: Strongly magnetic, one of the components of permanent magnets, and can show superparamagnetism under certain conditions.
Conductivity: Tetraferric oxide is a semiconductor, and its conductivity will change with temperature.
Solubility: It is insoluble in water, alkali solutions and most organic solvents, but can be dissolved in strong acids and produce iron and ferrous salts.
Chemical Properties of Tetraferric Oxide Fe3O4
The chemical properties of ferric oxide are more complex, mainly in the following aspects:
Acid-base reaction: react with strong acid to generate the corresponding iron salt and ferrous salt.
Reductive: can be reduced to metallic iron or ferrous oxide by hydrogen or carbon monoxide at high temperature.
Oxidizing property: under certain conditions, it can participate in oxidation reaction as oxidizing agent.
Stability: Stable in dry state, but easy to be further oxidized to other iron oxides in humid air.
Liganding ability: able to form complexes with a variety of ligands, which has important applications in catalysis and drug delivery systems. +
Production Methods of Tetraferric Oxide Fe3O4
