产品介绍
氧化钇稳定氧化锆 (IV)(YSZ)(超微粉)是一种氧离子导体,具有良好的离子电导率和高理化稳定性。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。 钇稳定氧化锆(YSZ)是用于固体氧化物燃料电池(SOFC)和氧传感器的最常用的固体电解质。YSZ表现出高氧离子电导率,而阻断电子电导率。YSZ颗粒可以由硝酸钇或异丙氧化物通过溶胶-凝胶法合成。[6]YSZ纳米颗粒可以在超临界水(SCW)中制备。可以通过基于CO2激光的连续/脉冲激光蒸发法获得具有不同%mol钇的不同尺寸的YSZ纳米颗粒。 应用 YSZ 可用于各种应用,例如: · 作为隔热涂层用于燃气轮机中金属部件的保护和隔热 · 制造固体氧化物燃料电池 (SOFC) 的电解质 · 制造氧化锆牙种植体基台 · 微能量转换装置用膜 · 用于催化应用的固体酸和催化剂 可以开发胶原-钇稳定的无定形氧化锆混合支架。YSZ薄膜可用作燃烧室、燃气涡轮机或柴油机的固定和旋转部件上的热障涂层。 用于固体氧化物燃料电池 (SOFC) 的电解质材料。 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 the 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 CO2 laser based continuous/pulsed laser vaporization method. Zirconium(IV) oxide-yttria stabilized (YSZ) (submicron powder) 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.
