Raman spectra are reported of chromium(VI) oxide species in Cr/Al 2O 3 catalysts, and of aqueous solutions of chromium oxide used for the preparation of these catalysts. The Raman spectra reveal that after impregnation and drying at room temperature under vacuum, the chromium oxide is present ...
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. Hazard Toxic by ingestion and inhalation. Flammability and Explosibility ...

It was obvious that the oxide Cr2O3, as a nucleating agent, stabilizes in the crystalline phase. Since the atoms in the lattice were in equilibrium, resulting in a long-range order in the crystalline phase, the Gibbs free energy reached the minimum. Therefore, the element Cr stabilized the...

For forty years, there has been a widely held belief that over 2,000 years ago the Chinese Qin developed an advanced chromate conversion coating technology (CCC) to prevent metal corrosion. This belief was based on the detection of chromium traces on the
