Description générale

Manganese powder is a free-flowing, brown to black powder with a high melting point (1244 °C) and exceptional resistance to corrosion and abrasion. Our high-purity manganese powder (≥99.9%) is a reliable and valuable material for various industrial and academic applications. The ability of manganese to exist in multiple oxidation states allows it to act as a redox mediator, facilitating electron transfer between reactants and products. This makes it an effective catalyst in a wide range of chemical reactions, including the oxidation of alcohols and the removal of pollutants from industrial emissions.

Application

Manganese powder is a cost effective alloying element with a high hardenability. It is majorly used in powder metallurgy applications such as:
  • a starting material for the preparation of manganese oxide for lithium ion batteries
  • a material used in surface alloying
  • sintering of steel to form manganese steel

Caractéristiques et avantages

Our 99.9% pure manganese powder is useful in powder metallurgical and chemical industries where purity matters most.
✔ Consistent quality
✔ High purity
✔ Available to scale up: bulk and pilot scale

Technologies are an integral part of our lives and we rely on them for such things as communication, heating and cooling, transportation, and construction. Improvements to technologies have made what they do for us more precise, automated, efficient, and powerful.

In recent years, the price of tellurium, a key component in the bestperforming thermoelectric materials, has increased significantly, leading to the question, “Is it economically viable to produce thermoelectric generators on an industrial scale?

The price of tellurium, a key component in many thermoelectric materials, has risen in recent years, leading to the search for more cost-effective substitutes. This article presents silicide materials as a cheaper potential alternative.
