applications of magnetite, iron oxide properties

Magnetite is multi-tasking! Its shape, fineness, chemical composition and colour make it ideal for many applications.

Applications

Water treatment

Magnetite is a material known for its ability to treat water contaminated with metals and organic micro-pollutants. Magnetite targets a wide range of pollutants by combining filtration removal with oxidative and reductive degradation. Among the pollutants targeted are arsenic, selenium, hexavalent chromium, chlorinated solvents, residues of medicines and phytosanitary products...

Soil remediation

Magnetite has the same action in groundwater as in water. Thus, heavy metals (hexavalent chromium, arsenic, lead, nickel etc.) can be captured, and organic pollutants such as chlorinated solvents (VOCs) can be removed from polluted soil.


Electromagnetic shielding

Magnetite, a "pure iron" ferrite, is a material known for its electromagnetic wave absorption properties: radar, wifi, microwaves etc. Integrated into films, paints, absorbent foams, our magnetite powder can be used in many ways: electromagnetic compatibility (EMC), anechoic chambers, stealth, etc.

Magnetic functionalisation

By introducing magnetite powders into a polymer, elastomer or foam matrix, an object can become sensitive to the magnetic field.

Induction heating

Magnetite acts as a susceptor and is capable of converting the energy of a variable magnetic field into heat. Magnetite powder can be used to give this function to a composite. 

Catalysis

Magnetite is used to accelerate some chemical reactions. It is for instance used in the Haber process for the production of ammonia from nitrogen.
