A NEW METHOD TO DETERMINE THE SIZE DISTRIBUTION OF NANOCRYSTALLINE GRAINS AND ITS APPLICATION
测定纳米晶粒尺寸分布的新方法及其应用

A new method,Profile-fitting of X-ray diffraction spectroscopy (PFXDS) method,which was adopted to determine the size distribution of nanocrystalline grains,was introduced in this paper.Its theoretical model and basic hypothesis were clearly interpreted and its advantages and disadvantages were discussed in details.The PFXDS method was applied to the size distribution calculation of nano-SnO2 powder produced by sol-gel technology and the relatively ideal results were obtained.
