Product Application of Zirconium dioxideCAS#1314-23-4
Zirconium dioxide (ZrO2) as an abrasive is used to make grinding wheels and special sandpaper. It is also used in ceramic glazes, in enamels, and for lining furnaces and high-temperature molds. It resists corrosion at high temperatures, making it ideal for crucibles and other types of laboratory ware. ZrO2 is used as a "getter" to remove the last trace of air when producing vacuum tubes.
