氧化钇稳定氧化锆 (IV) (YSZ) （纳米颗粒）是一种氧离子导体，具有良好的离子电导性和高理化稳定性。它的其他特性包括良好的抗冲击性、低热导率和高热膨胀系数。氧化钇稳定氧化锆 (YSZ) 是固体氧化物燃料电池 (SOFC) 和氧传感器最常用的固体电解质。在阻断电子传导的同时，YSZ 表现出较高的氧离子电导率。硝酸钇或异丙醇可通过溶胶凝胶法合成 YSZ 颗粒。可在超临界水 (SCW) 中制备 YSZ 纳米颗粒。基于 CO2激光的连续/脉冲激光汽化方法，可获得不同尺寸的 应用 Zirconium(IV) oxide-yttria stabilized (YSZ) (nanopowder) is an oxygen ion conductor with properties such as good ionic conductivity and high physiochemical stability. Its other properties include excellent shock resistance, low thermal conductivity and a high coefficient of thermal expansion.Yttria-stabilized zirconia (YSZ) is the most commonly used solid electrolyte for solid oxide fuel cells (SOFCs) and oxygen sensors. YSZ exhibits high oxygen-ionic conductivity while blocking electronic conduction. YSZ particles may be synthesized from yttrium nitrate or isopropoxide by sol gel method. YSZ nanoparticles may be prepared in supercritical water (SCW). YSZ nanoparticles of different sizes with varying % mol of yttria may be obtained by CO2laser based continuous/pulsed laser vaporization method.Collagen-yttria-stabilized amorphous zirconia hybrid scaffolds may be developed. YSZ thin films may be used as thermal barrier coatings on combustors, stationary and rotating components of gas turbines or diesel engines. 6YSZ can be used for a variety of applications such as:a thermal barrier coating for the protection and insulation of metal components in gas turbinesan electrolyte in the fabrication of solid oxide fuel cells (SOFCs)in the fabrication of zirconia dental implant abutmentsmembranes for micro energy conversion devicesa solid acid and a catalyst for catalytic applicationsElectrolyte material for solid oxide fuel cells (SOFC).
