The invention discloses AlHfTaO6 ceramic powder and a preparation method and application thereof.According to the preparation method, Al2O3 powder, HfO2 powder and Ta2O5 powder are weighed according to the molar ratio of 1: 2: 1 to serve as raw materials, the molar ratio can promote the different raw materials to react according to a certain reaction path to generate a target product without generating by-products, unreacted phases are effectively prevented from being left in the product, and the product quality is improved. The AlHfTaO6 ceramic powder is prepared by ball milling, uniform mixing, dry pressing and roasting. The preparation method is simple in process, low in equipment requirement and short in preparation period, the AlHfTaO6 ceramic powder which is single in phase, high in dispersion and fine and uniform in particle size can be prepared by controlling high-temperature roasting process conditions, and the AlHfTaO6 ceramic powder can be used for preparing high-temperature-resistant thermal protection environmental barrier coatings for aero-engines and rocket engine hot end components. In addition, raw materials required by the method are wide in source and low in cost, and the method can be popularized to industrial production.
本发明公开一种AlHfTaO6陶瓷粉体及其制备方法、应用，该制备方法以摩尔比为1:2:1称取Al2O3粉体、HfO2粉体和Ta2O5粉体为原料，该摩尔比可促进不同原料按一定反应路径反应生成目标产物而不产生副产物，并有效防止产物中残留未反应物相，通过球磨混匀、干压成型和焙烧制得AlHfTaO6陶瓷粉体。该制备方法工艺简单、设备要求低、制备周期短，通过控制高温焙烧工艺条件，可制备得到物相单一、高分散、粒径细小均一的AlHfTaO6陶瓷粉体，可用于制备航空发动机、火箭发动机热端部件用耐高温热防护环境障涂层。此外，该方法所需原材料来源广、成本低，可推广至工业化生产。
