MagSpire
MagSpire for Industry – liquid natural magnetite
MagSpire IS-3903 is micronised natural magnetite (Fe3O4) in liquid, water-based form from IonSpire Materials AS. It is made for industrial applications where magnetite is needed, for example magnetic paints and coatings. MagSpire is tailored to the customer: fineness and properties are specified together with you according to your application, so we do not state fixed technical values. Other examples of applications for magnetite are drilling fluids, heavy concrete and radiation shielding, water treatment and friction materials. These are examples, not a specification. Describe your application and request a quote, and we will find out together whether MagSpire suits it. A sample can be arranged, and testing in your own application is recommended.

-
Catalysts
Magnetite is the precursor of the iron catalyst used in ammonia production. Requires high purity.
Documented use

-
Ferrites and electronics
Very pure magnetite can be an iron source for ferrites, but requires very low impurities.
Niche / few sources

-
Magnetic paints and coatings
Finely ground magnetite in paints and coatings makes walls, boards and other surfaces receptive to magnets.
Documented use

-
Dense medium separation (DMS)
Ground magnetite in water forms a dense suspension that separates materials by density, e.g. in coal washing, mineral processing and recycling. The magnetite is recovered magnetically.
Well-documented use

-
Heavyweight and radiation-shielding concrete
Magnetite as heavy aggregate gives high-density concrete, used for radiation shielding in hospitals and nuclear facilities. Mostly coarse fractions are used.
Well-documented use
Sources: The Concrete Society – Radiation shielding concrete · ASTM C637 – Aggregates for radiation-shielding concrete
-
Pipeline concrete weight coating
Concrete coatings with magnetite give subsea pipelines negative buoyancy. Here too, mostly coarse fractions are used.
Well-documented use
Sources: LKAB Minerals – Concrete weight coating · QMAG – Pipe coatings
-
Counterweights and dense fillers
High density gives a lot of weight in a small volume, e.g. in counterweights and sound- and vibration-damping composites.
Documented use

-
Water treatment
Magnetite is used as ballast for rapid settling in treatment plants and is recovered magnetically.
Well-documented use

FAQ
Frequently asked questions
What is MagSpire IS-3903?
MagSpire IS-3903 is micronised natural magnetite (Fe3O4) in liquid, water-based form from IonSpire Materials AS. It is tailored to the customer: fineness and properties are specified together with you according to your application.
What can MagSpire be used for?
MagSpire is made for industrial applications where magnetite is needed. Examples are magnetic paints and coatings, drilling fluids, fertiliser (micronutrient), toners and printing inks, catalysts, ferrites and electronics, heavy concrete and radiation shielding and weight coating of pipelines, as well as dense medium separation (DMS), counterweights and heavy fillers, water treatment, friction materials and brake pads, welding electrodes and abrasives and waterjet cutting. These are examples, not a specification: request a quote, and we will find out together whether it suits your application. A sample can be arranged. MagSpire can be supplied without preservative. Whether the product should contain a preservative is agreed with the customer based on the application. Requirements in regulated applications are clarified before delivery.
Does MagSpire IS-3903 have fixed technical values?
No. MagSpire is tailored to the customer, and fineness and properties are agreed in the specification for your application. That is why we do not state fixed technical values.
