 Oxide AMERICAN ELEMENTS)
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.
