Application
Chromium(III) oxide (Cr2O3) has been used as a standard for the determination of chromium content in cattle feces by employing different digestion techniques.1 It has also been employed as a digestibility marker in a study.
Used in a solid-state reaction to form the new ternary oxide, CrVMoO7, can be used in selective oxidation.
Used in a solid-state reaction to form the new ternary oxide, CrVMoO7, which should find application in selective oxidation. Its crystal structure was also determined.
General description
Chromium(III) oxide is also referred to as chromic oxide. It is commonly employed as a marker in various digestion assays conducted on animals.
Chromium(III) oxide is mainly used as a green pigment in paints, inks and ceramics. On a commercial scale, it is synthesized by the reduction of sodium chromate with sulfur.
