Tantalate ceramic with low oxygen diffusion as well as preparation method and application of tantalate ceramic
The invention belongs to the technical field of oxygen barrier coatings, and particularly relates to tantalate ceramic with low oxygen diffusion as well as a preparation method and application of the tantalate ceramic. The chemical formula of the tantalate ceramic with low oxygen diffusion provided by the invention is Re3TaO7, and Re is one or more of La, Ce, Nd, Sm, Eu, Gd, Dy, Ho, Er, Yb and Y. The tantalate ceramic provided by the invention has high-temperature heat insulation performance, high-temperature stability and low-oxygen diffusion performance, and can be used as a thermal barrier coating to effectively inhibit metal oxidation and oxidation layer thickening, so that the service life is greatly prolonged.
本发明属于阻氧涂层技术领域，具体涉及一种具有低氧扩散的钽酸盐陶瓷及其制备方法和应用。本发明提供的具有低氧扩散的钽酸盐陶瓷的化学式为Re3TaO7，其中，Re为La、Ce、Nd、Sm、Eu、Gd、Dy、Ho、Er、Yb和Y中的一种或几种。本发明提供的钽酸盐陶瓷具有高温隔热性能、高温稳定性和低氧扩散性能，其作为热障涂层可以有效抑制金属氧化和氧化层增厚，大幅度延长使用寿命。
