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。[1][2][3]
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。[4]YSZ表现出高氧离子电导率,而阻断电子电导率。[5]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。[7]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。[8]

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[2]
  • 制造固体氧化物燃料电池 (SOFC) 的电解质[9]
  • 制造氧化锆牙种植体基台[10]
  • 微能量转换装置用膜[11]
  • 用于催化应用的固体酸和催化剂[12]

可以开发胶原-钇稳定的无定形氧化锆混合支架。[5]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。6
