陶瓷粉体粒径的测量

Particle Size Determining of Ceramic Powder

组成粉体的固体颗粒粒径大小对粉体系统的性质有很大的影响 ,随着纳米技术的发展 ,如何更好的表征纳米粉体 ,最主要的一个参数就是粉体颗粒的大小 ,而数据的获得需要通过各种测量方法来得到。笔者综述了陶瓷粉体粒径常用的测试方法 ,并以水热法制备的钛酸钡陶瓷粉体粒径的测定为例讨论了各种测试方法的适用范围及优缺点。

It is very important for ceramic powder that particle size has great influence on properties of ceramic powder. With the development of nanotechnology,how to characterize nanopowder,best of all,the particle size should be correctly obtained by different testing methods.Commonly testing methods of ceramic powder size are summarized, the applying condition and advantages and disadvantages of some methods are discussed by determining barium titanate powder of hydrothermal synthesis in the paper.
