Yttria-stabilized zirconia (YSZ) is a ceramic in which the cubic crystal structure of zirconium dioxide is made stable at room temperature by an addition of yttrium oxide. These oxides are commonly called "zirconia" (Zr O 2) and "yttria" (Y 2 O 3), hence the name.

Yttria-stabilized zirconia (Y-TZP) was developed to overcome crack propagation presented by aluminized ceramics. Yttrium dioxide is added to pure zirconia to stabilize the tetragonal phase at room temperature, resulting in a polyphasic material known as stabilized zirconia.

Explore the properties, synthesis, and applications of Yttria-Stabilized Zirconia (YSZ), a high-performing ceramic material.

2024年11月8日 · Yttria stabilized zirconia is a ceramic material that is formed to stabilize the cubic crystal structure of zirconium dioxide at room temperature. Yttria stabilized zirconia is a popular choice for applications that require a high temperature-resistant, wear-resistant, oxidation-resistant, and strong material.

2024年2月5日 · By introducing small amounts of stabilizing oxides, such as yttria (Y2O3), calcia (CaO), and magnesia (MgO), it is possible to maintain the zirconia in a tetragonal or cubic phase at room temperature, effectively preventing the detrimental phase transitions.

Yttria-stabilized zirconia (Y-TZP) was developed to overcome crack propagation presented by aluminized ceramics. Yttrium dioxide is added to pure zirconia to stabilize the tetragonal phase at room temperature, resulting in a polyphasic material known as stabilized zirconia.

Yttria-Stabilized Zirconia is a material that exhibits excellent ionic conductivity due to the presence of oxygen vacancies, allowing the movement of oxygen ions at relatively high temperatures, typically between 500-1000 °C.

Yttria-stabilized zirconia (YSZ) is well-known as a material with perfect mechanical, thermal, and electrical properties. It is used for manufacturing various high-temperature components for aerospace and energy generation, as well as wear- and corrosion-resistant devices in medicine.

2023年4月3日 · Yttria (Y 2 O 3) is one of the most common stabilizers for zirconia and formed yttria stabilizer zirconia (YSZ). The phase transition of YSZ is complicated but is well documented as the sintering temperature and the yttria concentration vary.

2019年10月27日 · A conventional SOFCs operates at high temperature, typically ranges between 800 to 1000°C. SOFCs use yttria-stabilized zirconia (YSZ) as the electrolyte, which exhibits excellent oxide ion conductivity in this temperature range. However, this temperature range poses an issue to SOFCs durability, as it leads to the degradation of the cell ...
