摘　　要：二氧化锆纳米粉体是制造高科技氧化锆系陶瓷的重要原材料。纳米粉体的制备方法有很多种 ,但由于水热法可以控制微粉的粒径、形态、结晶度和组成 ,所以水热法是目前生产纳米粉体方法中最具发展潜力的工艺方法之一。国内外对水热法的研究已有相当进展 ,并正向工业化迈进。对目前国际上出现的应用于制备纳米二氧化锆系粉体的各种水热方法进行了介绍 ,着重介绍了制备过程中应用的各种新技术 ,并展望了水热法的发展前景。Nanopowders of zirconia are the important feedstock of production of the high tech ceramics of the zirconia system. There are many ways to obtain the nanometer materials, however, producing the fine powder with controlling the size, phase, composition and the degree of crystallized can be achieved by hydrothermal method, so hydrothermal method now becomes one of the most potential technologies in preparation of nanometer powders. The studies of the hydrothermal method have made a great progress in the international field, and are now investigating how to industrialize. Preparation methods of nanometer zirconia powder at the present time in the international level were reviewed, which emphasizes the new hydrothermal technologies. And the development of hydrothermal method is discussed.
