Gadolinium praseodymium zirconate ceramic target material, preparation method and application thereof
The invention provides a praseodymium gadolinium zirconate ceramic target material, a preparation method and application thereof, the chemical formula of the praseodymium gadolinium zirconate is (Gd1-xPrx) 2Zr2O7, and x is more than 0 and less than or equal to 0.15. By adopting the mode of first low-temperature sintering, processing and then secondary sintering, the mechanical property of the zirconium acid gadolinium praseodymium ceramic target material can be improved, compared with the zirconium acid gadolinium, the zirconium acid gadolinium praseodymium ceramic target material has lower thermal conductivity and higher thermal expansion coefficient, and the thermal cycle performance and high-temperature stability of the aero-engine thermal barrier coating can be improved through the lower thermal conductivity; the higher thermal expansion coefficient is beneficial to matching of the thermal barrier coating and the substrate, and the thermal cycle life of the coating is prolonged.
本申请提供一种锆酸钆镨陶瓷靶材、制备方法及其应用，所述锆酸钆镨的化学式为(Gd1‑xPrx)2Zr2O7，其中，0＜x≤0.15。采用先低温烧结、经加工后再进行二次烧结的方式，能够改善锆酸钆镨陶瓷靶材的力学性能，相比锆酸钆具有更低的热导率和更高的热膨胀系数，更低的热导率有利于提升航空发动机热障涂层的热循环性能和高温稳定性，更高的热膨胀系数有利于热障涂层与基底的匹配，提升涂层热循环寿命。
