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.
Amphoteric chrome oxide is the only stable oxide of chromium metal and can be used at all temperatures to 1200C. This leaves a margin before it begins to volatilize around 1240C, the fumes are very toxic.
