一般描述

Chromium (III) oxide is a chromium complex in which the chromium ion is in +3 oxidation state. The synthesis of its sub-micron powder has been reported.† The IR and Raman spectra of chromium (III) oxide have been studied.† The impact of adding lysozyme on the stability of chromium (III) oxide (Cr2O3) suspension has been evaluated.†

应用

Chromium (III) oxide may be used in the following processes:
  • To modify carbon paste electrodes for optimizing its ability to detect nitric oxide.
  • Preparation of Ni+Cr2O3 composite coatings.
  • Formation of the ternary oxide, CrVMoO7 by solid-state reaction which may be employed in selective oxidation reactions.
用于形成新型三元氧化物 CrVMoO7 的固态反应,此三元氧化物可用于选择性氧化。
