Chromium Oxide (Cr 2 O 3) Production. The first transparent hydrated form of Chromium (+3) was prepared and made by the Parisians Pannetier and Binet in 1838. It has a secret process that is being manufactured from Chromite (Fe, Mg) Cr 2 O 4 which is used to produce Chromium (III) Oxide. Chromite was found in the mines of southern Africa, Asia, Turkey, and Cuba.
