Rare Earth Metal Salts

Rare earth elements touch every facet of modern life. We benefit from technologies that utilize rare earth metal salts every time we talk on a cell phone, use a computer, receive medical treatment, drive a car, or simply watch TV.

Rare earth halides, nitrates, and acetates shown in the products table below have recently attracted a substantial amount of attention from our customers involved in both academic and industrial research and development. While these metal salts are easily available in research quantities from our online catalog, ProChem also offers exclusive customized high purity forms of the same materials which are manufactured in house to the strict specifications of our diverse high-tech customers.

Products offered by Prochem are often used as battery additives,¹precursors in catalysis,²  in synthesis of nanomaterials,³ metal organic frameworks (MOFs),⁴ complex oxides and ceramics,⁵ as well as for the preparation of photoluminescent and scintillator materials,^6,7 to name only a few examples. A wider selection of rare earth-based products can be found on ProChem’s product search page.
