Measuring Technique of the Grain Size of Ceramic α-Al_2O_3

本文介绍了电子显微镜、X射线衍射、氮吸附小比表面法、红外光谱结构分析、研磨法等用于陶瓷氧化铝晶粒度测定的情况 ,通过对比 ,指出了电子显微镜能够真实地反映微观世界 。

The article introduced the measuring technique of the grain size of ceramic alpha alumina, including electronic microscope, Laue X-ray diffraction, nitrogen absorption specific surface area, infrared spectra and grinding method. It is concluded that the grain size of ceramic alpha alumina can be observed directly by electronic microscope,and it is the best way of the measurement.
