Yttrium stabilized zirconium is a kind of non-toxic, tasteless, white powder. Yttrium stabilized zirconia has enough stability in alkali solution and lots of acid solution, except hot concentrated H2S04, HF and H3P04. It enjoys excellent properties of ceramic, such as strong thermal shock resistance, high temperature resistance and good chemical stability. Yttrium stabilized zirconia compound other materials (Al2O3, SiO2) which could greatly improve the performance of material parameters, the fracture toughness, flexural strength, and etc. Make high-tech composite materials with high temperature resistance, corrosion resistance, wear resistance and other good characteristics. Meanwhile, under the certain conditions, the composite materials can display the electric, magnetic, optical, acoustic and other special functions. The heat insulating and high temperature of ZrO2 composite materials is the best in a variety of metal oxide ceramic materials. Stabilized zirconia is an important component of senior ceramic pigment and glaze, it is suitable to be made into ceramic coating and high-temperature refractory products. Zirconia Yttria is an important kind of Zro2 structure ceramic materials, with the phase transformation toughening properties, good mechanical properties, high fracture toughness and bending strength, have the lowest thermal conductivity but thermal expansion coefficient is close to metal materials. Stabilized zirconia also is a wonderful material to be made into solid electrolyte, also can be used for SOFC electrolyte and high-temperature heater. Stabilized zirconia is widely used in electronic ceramics, structural ceramics, biological ceramics, high-grade refractory materials, piezoelectric element, radio components, optical lenses and other industries.
