Inorganics - Chromium and its Compounds
The majority of chromium extracted out of the ground globally is used as an additive to steel, in the form of ferrochrome. For this reason, the primary chromium chemicals produced annually are chromium trioxide, chromium (III) oxide, and sodium chromate. All other chromium chemicals are derived from these feedstock materials.
Chromium chemicals are used in a multitude of established as well as emerging applications. Established uses for chromium chemicals include catalysts, glass and glaze coloring additives, pyrotechnics, and metallurgical additives.
Emerging uses for chromium compounds include batteries, pharmaceutical precursors, and electro-optic materials. Chromium is unique in that it offers a range of redox chemistries, including High Valence Metal (i.e. hexavalent) compounds, as well as Low Valence Metal divalent compounds.
Due to this range of properties, chromium compounds span a wide range of physicochemical characteristics.
GFS Chemicals offers a complete range of chromium chemistries suitable for industrial as well as analytical applications. Please e-mail inorganicdevelopment@gfschemicals.com for further information regarding the existing chromium chemistries currently available.
