精细陶瓷（先进陶瓷、先进技术陶瓷）—采用电感耦合等离子体光发射光谱法对二氧化硅粉末中金属杂质进行化学分析的方法

[中文适用范围]： 本标准规定了精细陶瓷原料二氧化硅粉体中金属杂质的化学分析方法。规定了酸分解二氧化硅粉体中金属杂质元素的测定方法。用电感耦合等离子体发射光谱法（ICP-OES）测定试验溶液中的铝、镉、钙、铜、铁、铅、锂、镁、锰、镍、钾、钠、钛、锌和锆的含量。 [外文原描述]： This document specifies methods for the chemical analysis of metal impurities present in silicon dioxide powders used as a raw material for fine ceramics. It stipulates the methods for the determination of metal impurity elements in silicon dioxide powders that are decomposed by acid decomposition. The aluminium, cadmium, calcium, copper, iron, lead, lithium, magnesium, manganese, nickel, potassium, sodium, titanium, zinc and zirconium contents in the test solution are determined by inductively coupled plasma-optical emission spectrometry (ICP-OES).
