摘要:纳米陶瓷是一种新型纳米材料，是现代陶瓷技术发展的最新领域。纳米陶瓷县有一些普通陶瓷所没有的优越性,如高硬度、高韧性、低温超塑性、易加工性等。为了使纳米陶瓷具有优良的性能必须要有高纯度、化学组成均匀、颗粒大小能满足要求且粒度分布较窄的纳米陶瓷粉体作为原料。本文中主要介绍了纳米陶瓷粉体的制备方法:固相法、液相法和气相法，并分析比较了不同方法的优点与不足。

Abstract: Nano-ceramic particles is a new type of nanometer materials,which is the up-to-the-minute field in the development of modern ce-ramic technology. Nano-ceramic partjcles possessed some predominant ca-pability, such as high rigidity, high toughness,super plasticity in the lowtemperature 、machining easily and so on. In order to possess these excellentcharacters, nano-ceramic particles must satisfy high purity, well-distributedchemical component, proper granule size and narrower distribution. Thepreparation technologies of nano-ceramic particles are chiefly introduced.such as solid - phase - method, liquid - phase - method and vapor -phase - method. The advantages and disadvantages of all methods are ana-lyzed.
