Many high-temperature alloys rely on the development of a chromia-containing scale for protection against oxidation and corrosion. In particular at higher temperature or in tough environments, the rate of oxidation becomes too great for iron oxide forming steels and therefore stainless steels (> 9% Cr) are used instead.There is a great number of publications concerning …

Chromium(III) oxide is a precursor to the magnetic pigment chromium dioxide by the following reaction: [8] Cr 2 O 3 + 3 CrO 3 → 5 CrO 2 + O 2. Along with many other oxides, it is used as a compound when polishing (also called stropping) the edges of knives, razors, surfaces of optical devices etc. on a piece of leather, balsa, cloth or other ...

Structure and properties. Cr 2 O 3 adopts the corundum structure, consisting of cubic close packed oxides with 2/3 of the octahedral holes occupied by chromium. It is an amphoteric oxide, dissolving in acids to give chromium(III) salts and in molten alkali to give chromites. Production. The Parisians Pannetier and Binet first prepared Cr 2 O 3 in 1838 via a secret process.

Impregnation of chromium oxide into porous, amorphous silica-alumina followed by calcination in dry air at 400–800 °C produces a precatalyst that presumably is reduced by ethylene during an induction period to form an active polymerization catalyst (Figure 7). 2 Other supports such as silica, alumina, and titanium-modified silicas can be used and together with physical factors …

X-ray diffraction studies showed that the coatings were of hcp rhombohedral α-phase chromium oxide. Cr O x coating samples were found to grow preferentially towards the (110) crystal orientation of α-Cr 2 O 3 . Texturing was found to depend on the orientation of the substrates relative to the targets and also on the nature of substrates.

A catalog of pigments printed around 1840 lists a green oxide of chromium believed to be chromium oxide. Also, in 1969, Kühn found chromium oxide in three paintings dated between 1845 and 1850 using microscopy and emission spectroscopy. It is widely accepted that chromium oxide was used before the hydrated version.
