Yttria stabilized zirconia
Your current location is: Website home page " Ceramic material " Zirconium oxide " Yttria stabilized zirconia

Yttrium oxide is used as stabilizer, which is mainly a tetragonal structure. The bending strength of all zirconia materials is the highest, especially when sintering is suppressed. Yttria stabilized zirconia has fine grain size and is suitable for cutting in a cutting tool because of its high wear resistance.

Yttria stabilized zirconia can be used for making crucible for vacuum induction melting, high purity zirconium sizing nozzle or zirconium composite long nozzle brick used for steelmaking, and lining for lining with high temperature over 1800 C and gaseous lining for gas reaction furnace. Zirconia products can be made into high temperature furnace heaters, high temperature furnace tubes, wire drawing dies and so on because of their semiconductor properties. Zirconia elements and zirconia elements of various oxygen determinations can also be made continuously in high temperature solution. Fused zirconia can be used as aggregate for zircon amorphous materials, casting sand for titanium alloys and plasma spraying materials. With the development of science and technology, the use of stabilized zirconia is expanding to different fields.

The excellent grain of yttria stabilized zirconia makes the ceramics densely produced, without many pores, and has excellent mechanical strength, corrosion resistance, impact toughness, thermal shock resistance and very low thermal conductivity. Due to these characteristics, yttria stabilized zirconia is mainly used in wear-resistant parts, cutting tools and thermal barrier coatings.
