The invention discloses a preparation method of LLZTO granulated powder, wherein the preparation method comprises the steps: carrying out ball-milling dispersion on LLZTO powder in a polyvinyl butyralester solution, carrying out spray drying by using a spray dryer special for ethanol to obtain the granulated powder, and selecting nitrogen as a drying medium. The LLZTO powder is made into the granulated powder through spray drying, particles are uniform and controllable, good fluidity is achieved, and it can be guaranteed that no internal stress exists in the forming and sintering process in the dry pressing forming process; the LLZTO powder is made into the granulated powder by using a special spray dryer for ethanol, so that the purity of the powder in the spray drying process is ensured.
本发明公开了一种LLZTO造粒粉的制备方法，LLZTO粉体在聚乙烯醇缩丁醛酯溶液中球磨分散，使用乙醇专用喷雾干燥机经过喷雾干燥成为造粒粉，干燥介质选择氮气。本发明通过使用喷雾干燥将LLZTO粉体制备成为造粒粉，颗粒均匀且可控，具有良好的流动性，在干压成型过程中可以保证成型及烧结后无内应力存在；本发明通过使用乙醇专用喷雾干燥机将LLZTO粉体制备成为造粒粉，保证喷雾干燥过程中粉体的纯净。
