When the starting material was the crystalline powder of Cr 2O 3, the oxidation reaction proceeded extremely slowly. The rapid formation of CrO 2 from Cr(OH) 3 compared with that from Cr 2O 3 is partly attributed to the existence of CrOOH which is produced as an intermediate phase in ...

A common trend of deoximation was established from electronically tuned aldoximes, which is: aliphatic>aromatic>aldoximes with strong electron-withdrawing group, though the extent of deoximation was less in case of CrO 2. Above effects were not observed with chloramine-T and diacetoxyiodobenzene, ...
In recent years, some modelling efforts have focused on self-diffusion coefficients in pure Cr, Cr2O3, and Cr-containing alloys using density functional theory20,21,22,23. While each of these approaches provides its own insights on the nature of point defects’ charge state, mobility, and ...
