Moderate Cost: YSZ substrates offer a cost-effective solution for various applications.
Wear-Resistance: The material exhibits high wear resistance, making it suitable for demanding applications.
Good Match with Oxides: YSZ substrates have good compatibility with multiple single and multiplication oxides, allowing for versatile use in different applications.
Early Application in Superconducting Thin Films: YSZ was one of the earliest materials used for stabilizing high-temperature superconducting thin films of YBCO.
Applications: Solid Oxide Fuel Cells (SOFCs), Thermal Barrier Coatings (TBCs), Oxygen Sensors, Medical Implants, Electronics, etc.
Kingwin Optics’ Yttria Stabilized Zirconia (YSZ) single-crystal substrate is a high-quality material manufactured by adding 8-13 mol% of Yttrium to Zirconium Oxide (Zirconia) melts. This addition acts as a stabilizer, preventing the Zirconia from breaking up during the cooling process. The resulting YSZ single crystals offer moderate cost, excellent wear-resistance, and good compatibility with multiple single and multiplication oxides.
