以下找了一个案例,希望对楼主的判断有帮助。个人认为首先要了解你要研究的材料基本特征,然后再讨论使用什么样的仪器。当然也要考虑效益!
This is a high resolution SEM-picture of destinezite from Richelle, near Visé, Liège Province, Belgium. The nodules found in Belgium are dull, beige colored, looking rather amorphous and pulverulent. But at very high magnification (in this picture 23800 X) well formed six-sided plates can be observed. Those platelets are about 1.5 X 3 µm "tall" 0.0015 X 0.003 mm). Note that this mineral is not hexagonal, but triclinic !
