From: Handbook … 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. Although insoluble in water, it reacts with acid to produce salts of hydrated chromium ions … See more Cr 2O 3 occurs naturally as the mineral eskolaite, which is found in chromium-rich tremolite skarns, metaquartzites, and chlorite veins. … See more Because of its considerable stability, chromia is a commonly used pigment.

Chromium(IV) oxide - Wikipedia
WebChromium(II) oxide (CrO) is an inorganic compound composed of chromium and oxygen. It is a black powder that crystallises in the rock salt structure. Hypophosphites may reduce chromium(III) oxide to chromium(II) oxide: H 3 PO 2 + 2 Cr 2 O 3 → 4 CrO + H 3 PO 4. It is readily oxidized by the atmosphere. WebJul 29, 2014 · Step 1.
