摘　　要：纳米氧化锆由于粒子间的量子效应、小尺寸效应、表面效应和宏观量子效应等,使其在化学、力学、热学、电学等方面的性能表现更为优异,在陶瓷、热障涂层、生物材料、通讯信息等众多领域获得了广泛应用。但是纳米氧化锆在生产过程中会存在粉末团聚严重、粒度分散以及在相变过程导致的体积变化和剪切应力,导致纳米氧化锆粉体性能指标难以达到材料应用的要求。文章介绍了稳定氧化锆纳米材料的应用领域,并结合当前研究的现状,梳理了稳定氧化锆纳米材料制备方法,分析不同制备工艺存在的优缺点。认为研究具有良好分散性、粒度分布窄的高纯稳定氧化锆纳米材料是今后的发展趋势,开发工艺简单,产品质量稳定,生产成本低的制备方法,是实现纳米氧化锆材料制备工业化生产的关键所在。Due to the quantum effect, small size effect, surface effect and macroscopic quantum effect among particles, nano-zirconia has more excellent performance in chemistry, mechanics, heat, electricity and other fields, and has been widely used in ceramics, thermal barrier coatings, biological materials, communication and information and other fields. However, in the production process of nano-zirconia, there will be serious powder agglomeration, particle size dispersion, volume change and shear stress caused by phase transformation, which makes the performance index of nano-zirconia powder difficult to meet the requirements of material application. The application fields of stabilized zirconia nanomaterials are introduced, and the preparation methods of stabilized zirconia nanomaterials are combed according to the current research status, and the advantages and disadvantages of different preparation processes are analyzed. It is believed that the research of high-purity stable zirconia nanomaterials with good dispersion and narrow particle size distribution is the development trend in the future, and the development of a preparation method with simple technology, stable product quality and low production cost is the key to realize the industrialized production of nanometer zirconia materials.
