利用PowderX软件绘制Y_3Al_5O_(12)粉体的XRD图谱,介绍其用于无机材料化学实验课程;还可根据衍射数据计算晶面指标;利用软件画出的衍射图读取的半峰宽数据,可以计算粉体颗粒粒径。在无机材料化学实验教学中使用PowderX软件,可以直接得到XRD图谱,既免去繁琐的手工绘图,节约了时间,计算中,又可以加深学生理解基础概念和提高应用计算机的技能。
The XRD patterns of Y_3Al_5O_ (12) powders were drawn by PowderX software and introduced to the chemical experiment course of inorganic materials. The crystal surface index can also be calculated according to the diffraction data. The half-width data read by the software can be Calculate the particle size of the powder. The use of PowderX software in inorganic materials chemistry experiment teaching can directly obtain the XRD pattern, which can save the time, calculation and the students’ understanding of the basic concepts and improve the computer skills by eliminating cumbersome manual drawing.
