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。
In order to possess these excellent characters, nano-ceramic particles must satisfy high purity, well-distributed chemical component, proper granule size and narrower distribution.
以AOT改性氧化镁可使氧化镁表面与AOT发生化学键合，从而可得到分散性好、更加稳定，粒度更均匀的纳米氧化镁颗粒。
Modifying the magnesia with AOT, can make the surface of magnesia connect with AOT by chemical bond, obtaining more stably and equally nanomagnesia particles.
结果表明：名义尺寸相同而实际尺寸相差较大的磨球所磨出的粉体粒度大且分布不均匀，烧结体硬质相颗粒粗大且等轴性差，抗弯强度和硬度均较低。
It is found that the grain size of the powders milled by balls with different diameters is big, the hard phase is big too and not uniform, the hardness and bending strength are also lower.
