Rare earth zirconate ceramic nano powder material and preparation method thereof
The invention discloses a rare earth zirconate ceramic nano powder material and a preparation method thereof. The preparation method comprises the following steps: weighing the rare earth salt and the zircon salt according to the corresponding proportion, preparing the rare earth salt and the zircon salt into solutions, and mixing; adding ammonia water into the mixed solution as a precipitator, stirring for a certain time, and standing to obtain a complex precipitate; carrying out cross flow treatment on the obtained complex precipitate, repeatedly washing the obtained precipitate, and carrying out colloidal particle refining treatment to obtain a pure alkaline precipitate; mixing the obtained alkaline precipitate with a dispersing agent, and performing distillation and drying treatment in a certain vacuum environment at a certain temperature to obtain dry powder; carrying out rolling and grinding treatment on the obtained powder through a double-roller machine, and carrying out calcination treatment on the split body at a certain temperature; and feeding the calcined powder into a jet mill, and treating to obtain the nano-powder. The high-entropy nano rare earth zirconate powder can effectively prolong the service life of a coating.
本发明公开了一种稀土锆酸盐陶瓷纳米粉体材料及其制备方法。制备方法有如下步骤：称取相应比例的稀土盐和锆盐，将其配置成溶液后进行混合；混合溶液中加入氨水作为沉淀剂，搅拌一定时间后静置得到络合物沉淀；将获得的络合物沉淀进行错流处理，再将得到的沉淀物反复洗涤和胶粒细化处理，得到纯净的碱性沉淀物；将得到的碱性沉淀物与分散剂混合，在一定的真空环境中、一定温度下进行蒸馏和干燥处理，得到干燥的粉体；得到的粉体通过对辊机进行碾轧和研磨处理，再用一定温度对分体进行煅烧处理；将煅烧后的粉体送入气流粉碎机处理后得到纳米粉体。该高熵纳米稀土锆酸盐粉末能够有效的延长涂层使用寿命。
