WebMay 15, 2024 · Chromium oxide thin films are of incredible interests because of their wide variety of innovative applications. Different forms of chromium oxide phases, such as CrO, CrO 2, CrO 3, Cr 2 O, Cr 2 O 3, Cr 3 O 4 and Cr 8 O 11 exist, out of these Cr 2 O 3 is the most stable phase under normal condition [].Cr 2 O 3 has been broadly investigated due … Chromium(III) oxide (or chromia) is an inorganic compound with the formula Cr 2O 3. It is one of the principal oxides of chromium and is used as a pigment. In nature, it occurs as the rare mineral eskolaite. See more Cr 2O 3 has the corundum structure, consisting of a hexagonal close packed array of oxide anions with 2⁄3 of the octahedral holes occupied by chromium. Similar to corundum, Cr 2O 3 is a hard, brittle material ( See more The Parisians Pannetier and Binet first prepared the transparent hydrated form of Cr 2O 3 in 1838 via a secret process, sold as a pigment. It is derived from the mineral chromite, … See more Chromium(III) oxide is amphoteric.
