Rare earth stabilized zirconia nano-powder and preparation method thereof
The invention provides rare earth stabilized zirconia nano powder and a preparation method thereof, and belongs to the technical field of powder materials. The preparation method of the rare earth stabilized zirconium oxide nano-powder comprises the following steps: mixing and dissolving rare earth salt, zirconium salt and water to obtain a precursor solution; drying the precursor solution to obtain crystal salt; carrying out ball milling on the crystalline salt, a dispersing agent and an alkali metal reactant to obtain paste; adding water into the paste, and performing ultrasonic washing and suction filtration to obtain a pulp cake; drying the slurry cake to obtain precursor powder; and calcining the precursor powder to obtain the rare earth stabilized zirconium oxide nano powder. The preparation method provided by the invention is high in cost benefit, easy to operate, free of pollution and capable of effectively controlling soft agglomeration among crystal grains and effectively relieving the phenomenon that the crystal grains are too large, so that the prepared rare earth stabilized zirconium oxide nano powder has the characteristics of uniform particle size, high dispersity and high crystallinity.
本发明提供了一种稀土稳定氧化锆纳米粉体及其制备方法，属于粉体材料技术领域。本发明稀土稳定氧化锆纳米粉体的制备方法，包括以下步骤：将稀土盐、锆盐和水混合溶解，得到前驱液；将所述前驱液干燥，得到结晶盐；将所述结晶盐、分散剂和碱金属反应物进行球磨，得到糊状物；在所述糊状物中加入水，超声洗涤、抽滤，得到浆饼；将所述浆饼干燥，得到前驱粉体；将所述前驱粉体煅烧，得到稀土稳定氧化锆纳米粉体。本发明提供的制备方法，成本效益高、易操作、无污染且能有效控制晶粒之间的软团聚，有效缓解晶粒过大现象的发生，使制备的稀土稳定氧化锆纳米粉体具有粒度均匀、分散性高、结晶度高的特点。
