Yttria stabilized zirconia, YSZ is a kind of ceramic material. By adding Yttrium(III) oxide, the phase transformation temperature range of Zirconium dioxide can be changed to produce stable cubic crystals and tetragonal crystals at room temperature.
Pure zirconia is a monoclinic phase at room temperature. When the temperature rises to about 1173 ℃, it will transform into a tetragonal phase, and when it rises to 2370 ℃, it will transform into a cubic phase. At 2690 ℃, it will become a liquid phase.
Monoclinic phase (phase transformation temperature: 1173 ° C) tetragonal phase (phase transformation temperature: 2370 ° C) cubic phase (melting point/solidification point: 2690 ° C) liquid.
Pure zirconia is cooled from high temperature to room temperature, and after undergoing phase transformation temperature, the square crystal is transformed into monoclinic crystal. Due to its drastic volume change, the sintered product contains microcracks and is often unusable. Zirconium dioxide does not exist in cubic phase (fluorite crystal structure) at room temperature, but by adding other oxides, the temperature range of Zirconium dioxide stabilized in cubic phase can be greatly increased. The Zirconium dioxide doped with phase stabilizer is called stabilized zirconias.
Yttrium stabilized zirconia beads can be used in Electroceramics, magnetic materials, zirconia, silicon oxide, Zirconium(IV) silicate, titanium dioxide, pharmaceutical food, pigments, dyes, inks, and special chemical industries. Zirconia refractory materials: zirconia crucibles, zirconia refractory fibers, zirconia kiln materials. Zirconia structural ceramics: zirconia ceramic bearings, zirconia ceramic valves, zirconia grinding materials. Zirconia functional ceramics: zirconia ceramic balls for ballpoint pens, zirconia ceramic tools, zirconia high-temperature heating materials, zirconia bioceramics, zirconia coating materials, zirconia communication materials, zirconia oxygen sensors.
We produce YSZ powder by self-propagating hydrolysis process.Based on different content of Y2O3,we can produce different YSZ powder.Normal products are 3Y-YSZ powder-based,divided into compacted powder and non-compacted powder depending on the customers'requirements.The physical properties could meet customers'different requirements for dry pressing,isostatic pressing,injection,casting,injection moulding,slip casting and so on.
