The invention belongs to the technical field of preparation of ceramic targets, and in particular relates to a method for preparing ceramic targets for thermal barrier coatings. The ceramic target is yttria stabilized zirconia (YSZ) ceramic target, Gd 2 Zr 2 O 7 ceramic target, La 2 Ce 2 O 7 ceramic target, La 2 O 3 +CeO 2 +Gd 2 O 3 , La 2 O 3 +CeO 2 +Ta 2 O 5 , La 2 O 3 +CeO 2 +ZrO 2 +Y 2 O 3 ceramic targets, through mechanical mixing, granulation, high-temperature solid-state reaction, cold isostatic pressing, sintering , vacuum annealing, and cutting processing to obtain the ceramic target material of the target size; the purity of the ceramic target material prepared by the preparation method provided by the present invention is as high as 99.9%, which can effectively avoid problems such as segregation, splashing, and cracking. Uniform structure and high strength. |
