The balanced equation for the hydrothermal synthesis is: ![]() DuPont, by decomposing chromium trioxide in the presence of water at a temperature of 800 K (527 ☌ 980 ☏) and a pressure of 200 MPa. Acicular chromium dioxide was first synthesized in 1956 by Norman L. Preparation and basic properties ĬrO 2 was first prepared by Friedrich Wöhler by decomposition of chromyl chloride. It is still considered by many oxide and tape manufacturers to have been one of the best magnetic recording particulates ever invented. However, it is still used in data tape applications for enterprise-class storage systems. With the increasing popularity of CDs and DVDs, the use of chromium(IV) oxide has declined. It once was widely used in magnetic tape emulsion. ![]() Chromium dioxide or chromium(IV) oxide is an inorganic compound with the formula CrO 2. ![]()
