Allgemeine Beschreibung

Copper powder, 99.999% trace metals basis, is a fine powder that is typically red-brown in color. It is often produced through the reduction of copper oxide or other copper compounds using hydrogen or other reducing agents. Our powder is highly pure, with less than 15 ppm impurities such as lead, arsenic, and bismuth, making it suitable for a wide range of industrial and commercial applications. Copper is valued for its excellent electrical and thermal conductivity, high ductility, and resistance to corrosion.

Anwendung

High-purity copper powder is used in a variety of applications, such as in the production of electrical components and conductive coatings and as a catalyst in chemical reactions. Additionally, copper powder can be used in the production of various alloys and as a raw material for powder metallurgy.

Leistungsmerkmale und Vorteile

Our 99.999% pure copper powder is useful in the electronics and chemical industries where purity matters most.
✔ Consistent quality
✔ Ultra high purity
✔ Available to scale up: bulk and pilot scale

Additive Manufacturing of Permanent Magnets

Permanent magnets are an essential technology for energy conversion. Motors and generators are used to convert energy between electrical and mechanical forms.

Lanthanide Ions as Photon Managers for Solar Cells

Spectral conversion for solar cells is an emerging concept in the field of photovoltaics, and it has the potential to increase significantly the efficiency of solar cells. Lanthanide ions are ideal candidates for spectral conversion, due to their high luminescence efficiencies and rich energy level structure that allows for great flexibility in the upconversion and downconversion of photons in a wide spectral region (NIR-VIS-UV).
