YSZ Ceramic

Yttria-stabilized Zirconia YSZ, ZrO₂+Y₂O₃, is a non-toxic, odorless ceramic material. ZrO₂ is monoclinic crystal at room temperature, the phase transformation temperature range of Zirconia is changed to produce stable cubic and tetragonal crystals at room temperature by adding Yttria. Known as “ceramic steel”, Yttria-stabilized Zirconia is usually prepared by hot pressing, dry pressing and isostatic pressing sintering. As its phase transformation toughening mechanism, Yttria stabilized tetragonal Zirconia crystal ceramic has excellent mechanical properties such as high strength, high fracture toughness, high bending strength, mechanical impact resistance and high wear resistance at room temperature, high ionic conductivity, and excellent chemical corrosion resistance, good stability to acid, alkali, glass and molten metal except sulfuric acid and hydrofluoric acid.
