讨论:是不是含有Fe, Co,Ni元素的材料均不能做SEM? - 功能材料
只要将有磁性的材料进行消磁处理就可做SEM。 SEM采用磁透镜进行聚焦成像。 如果被测试样磁性较强,轻则干扰成像,重则被测试样粉末被吸附到镜头上,损坏仪器。 理论上,磁性是物质的一种属性,任何物质都有磁性。 因此要求试样完全没有磁性是不可能的,我们只能要求其磁性小于某一范围。 如果是热发射sem磁性要求要低一些,如果是场发射sem,则要求就要严格的多。 铁,钴,镍为铁系元素,其化合物磁性较强,因而一般不能直接测。 不全是吧。 像我的材料里就都 …

SEM中Ni和Al2O3区分 - 有奖问答 - 小木虫 - 学术 科研 互动社区
我做了一个Ni-Al2O3复合材料(原则上Ni是均匀分散在Al2O3基体)的SEM,图片上呈现出黑色的纳米颗粒大约10nm,请问能否根据材料特点判断出黑色纳米颗粒是镍(根据XRD计算表明镍粒径也大约10nm)?
