六氟化钨中金属粒子的分析方法研究

本文结合六氟化钨的性质,对六氟化钨中的金属粒子进行分析。由于六氟化钨具有腐蚀性而且遇水迅速反应生成三氧化钨和氟化氢,同时金属粒子密度大,只有测定液态六氟化钨中的金属粒子含量结果才是稳定准确的。设计了一个密闭的半定量取样管路,可以准确的完成对六氟化钨中金属粒子的取样。完成取样后,根据各种金属粒子的溶解性质,将所取金属粒子配成可以用于原子发射光谱分析的待测溶液,然后利用原子发射光谱分析即可以得到六氟化钨样品中各种金属粒子的含量。最终分析结果显示,生产的六氟化钨产品可以满足相关技术指标的要求,满足产业化生产的条件。

Analytical Method of Metal Granules in Tungsten Hexafluoride

This paper analyzes metal granules in WF6 according to the especial characters of WF6. Because WF6 has causticity and has a reaction with H2O immediately, at the same time, the metal granules have large density, in order to ensure analytical result is veracious, we must analyze the liquid state WF6, we designed a analytical system, which is airtight, half-quantificational and accomplishes sampling exactly. Then basing the different solvency, collocating the solution which can analyze using atomic emission s...
