精细陶瓷（高级陶瓷、高级工业陶瓷）.使用电感耦合等离子体发射光谱法对氧化铝粉末中杂质进行化学分析的方法

[中文适用范围]： 本文件规定了用作精细陶瓷原材料的氧化铝粉末中存在的杂质的化学分析方法。 氧化铝粉末通过酸压分解、酸分解或碱熔分解。 采用电感耦合等离子体发射光谱仪（ICP-OES）测定测试溶液中钙、铬、铜、铁、镁、锰、钾、硅、钠、钛、锌和锆的含量。 [外文原描述]： This document specifies methods for the chemical analysis of impurities present in aluminium oxide powders used as a raw material for fine ceramics. Aluminium oxide powders are decomposed by acid pressure decomposition, acid decomposition or alkali fusion. The calcium, chromium, copper, iron, magnesium, manganese, potassium, silicon, sodium, titanium, zinc and zirconium contents in the test solution are determined by an inductively coupled plasma-optical emission spectrometer (ICP-OES).
