理论分析和实验检测两方面的研究都证明晶体粒子超微化和晶格结构的微应变能使X射线的衍射峰变宽.这种使衍射峰变宽的现象被称为超微粒子的(?)化效应.利用X射线衍射仪对衍射峰的纯衍射宽度定量测定,可对超微粒子的粒径大小和晶格微应变的程度作定量地分析.并可进一步研究γ-三氧化二铁超微粉粒径与磁性能的关系.
Both theoretical analysis and experimental investigation prove that the micro-strain of crystal particles and the lattice structure can broaden the diffraction peak of X-ray, and the phenomenon of widening the diffraction peak is called ultra-fine particle. ) Effect.The quantitative determination of the pure diffraction width of the diffraction peak by X-ray diffractometer can quantitatively analyze the particle size of the ultrafine particles and the degree of the micro-strain of the lattice, and can further study the effect of γ-ferric oxide super- Relationship between Particle Size and Magnetic Properties.
