一种高纯钼中非金属杂质元素的分析方法，属于粉末冶金分析技术领域。采用采用高平燃烧红外吸收法、惰气脉冲导热法或/和惰气脉冲红外法对待测的高纯钼中C0N非金属元素的含量进行测定，然后再采用三位原子探针技术来获取非金属杂质元素在钼材料中的分布规律。采用本发明的方法，能够明确得到非金属元素的含量和分布规律，对应调控各阶段控制非金属杂质元素起到先导的作用。

A method for analyzing non-metallic impurity elements in high-purity molybdenum belongs to the technical field of powder metallurgy analysis. The high-level combustion infrared absorption method, the inert gas pulse heat transfer method or/and the inert gas pulse infrared method are used to determine the content of non-metallic elements in the high purity molybdenum to be measured, and then the three-position atom probe technology is used to obtain the non-metallic elements. The distribution of impurity elements in molybdenum materials. By adopting the method of the present invention, the content and distribution law of non-metal elements can be clearly obtained, and the control of non-metal impurity elements in each stage of corresponding regulation and control plays a leading role.
