ERACHEM serves the Electronics industry especially by manufacturing high quality Mn3O4 (Mangano Manganic Oxide) used in nanoscales applications, ferrites and soft ferrites applications.Our Mn3O4 (Mangano Manganic Oxide) is manufactured at Tertre, our Belgium facility. Aside for this product, we have the widest range of Manganese derivatives (Manganese Nitrates, Manganese Dioxides, Manganese Oxides) sometimes tailor made that are particularly suitable for highly demanding applications in terms of purity and consistency.

Nanoscale applications require the best

Electronic miniaturization requires consistent high quality raw materials. Even subtle variations in particle shape or chemical composition can dramatically affect electrical properties and the reliability of finished parts.

The widest range of Manganese based solutions, worldwide

ERACHEM has developed the highest expertise in this domain at two industrial sites located in Baltimore (USA) and Tertre (Belgium). ERACHEM offers the widest range of solutions worldwide.

Our Baltimore (USA) establishment satisfies the needs of world tantalum capacitor manufacturers, through manufacturing and sale of three Manganese concentrations of high purity manganese nitrate solutions, as well as manganese dioxide with highly controlled particle size.

From Nitrate to Dioxide, serving the Electronic industry

Baltimore (USA) also provides extremely pure salts such as Mn2O3 HPX, MnO2 HPX and MnCO3 UF with well characterized particle size distributions, in order to serve the needs of Multilayer capacitors, ZnO varistors, and NTC thermistor manufacturers.

Tertre (BEL) provides high purity Mn3O4 LH (Mangano Manganic Oxide) specifically designed to meet the electrical expectations of Iron Manganese Zinc and Iron Nickel Zinc soft ferrites manufacturers.
