Zirconia BricksYttrium or Calcium stabilizedZirconium OxideThe sand is used as the raw material and combined with a binder, formed under high pressure and then sintered at a high temperature of 1800°C. It is an excellent lining material for ultra-high-temperature kilns, not only capable of operating at temperatures up to 2500°C but also...Zirconia BricksGood chemical stability, low volatility, strong resistance to thermal shock, and acid and alkali corrosion resistance.Zirconia BricksNon-reactive even at 1900°C with molten metals like aluminum, iron, nickel, platinum, and with silicate and acidic slag; widely used in medium-frequency high-temperature furnaces, molybdenum wire furnaces, tungsten rod furnaces, gas furnaces, carbon black reactors, and more.
