Zirconia BricksYttrium or Calcium stabilizedZirconium OxideThe sand is used as the raw material and combined with a binder, then formed under high pressure and sintered at a high temperature of 1800°C. It is an excellent lining material for ultra-high-temperature kilns, with a service temperature up to 2500°C and more.Zirconia BricksGood chemical stability, low volatility, strong resistance to thermal shock, and resistance to acid and alkali erosion.Zirconia BricksNon-reactive even when heated to 1900°C with molten metals like aluminum, iron, nickel, platinum, silicate, and acidic slag; widely used in medium-frequency high-temperature furnaces, molybdenum wire furnaces, tungsten rod furnaces, gas furnaces, carbon black reaction furnaces, and more.
