CHROMIUM III OXIDE GREEN
Also known as Chromium (III) Oxide, it is used as an inorganic pigment in paints, architectural coatings, plastics, roofing tiles and ceramic tiles. Chrome Oxide Green is also used in heavy-duty applications in the construction of high temperature and abrasion-resistant refractory brick for glass and fiberglass.
Because of its considerable stability, chromia is a commonly used pigment. It was originally called viridian. It is used in paints, inks, and glasses. It is the colorant in "chrome green" and "institutional green." Chromium(III) oxide is a precursor to the magnetic pigment chromium dioxide, by the following reaction.
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 material. It is available in powder or wax form, and in this context it is known as "green compound
