摘要
Na_xWO_3化学性质稳定,Na_xWO_3中的钠含量分析比较困难。本文介绍了Na_xWO_3中钠含量的热分析方法、原子吸收光谱法及X-射线分析方法。研究结果表明,热分析方法具有快速、方便、准确等特点。
NaxWO3 is a non-stoichiometric compound in which the value of x is a variable failing in the range of 0<x<1. NaxWO3 is chemically inert, so it is difficult to determine sodium content in NaxWO3 by chemical analysis. This article relates to thermogravimetry, atomic absorption spectrometry and X-ray diffraction methods for determining sodium content in NaxWO3. It has been found that thermogravimetry has more advantages than other two methods.
