精细陶瓷（先进陶瓷 先进技术陶瓷） 使用电感耦合等离子体 光学发射光谱法对氧化钇粉末中杂质进行化学分析的方法

[中文适用范围]： 本文件规定了用于精细陶瓷原料的提纯高纯度氧化钇粉末中杂质化学分析的方法。 本文件适用于测定氧化钇粉末中的铝(Al)、钙(Ca)、钴(Co)、铁(Fe)和硅(Si)。氧化钇粉末采用微波消解法进行分解。铝(Al)、钙(Ca)、钴(Co)、铁(Fe)和硅(Si)的含量采用电感耦合等离子体发射光谱法(ICP-OES)进行测定。 本文件不适用于矿物提取和加工过程中产生的粗制未提纯粉末，该类粉末由ISO 24181-1涵盖。 [外文原描述]： This document specifies methods for chemical analysis of impurities in refined high-purity yttrium oxide (Y 2 O 3 ) powders used as a raw material for fine ceramics. This document is applicable for determination of aluminium (Al), calcium (Ca), cobalt (Co), iron (Fe) and silicon (Si) in yttrium oxide powders. Yttrium oxide powders are decomposed by microwave decomposition method. The aluminium (Al), calcium (Ca), cobalt (Co), iron (Fe) and silicon (Si) contents are determined by using inductively coupled plasma-optical emission spectrometry (ICP-OES). This document does not apply to coarse unrefined powders from mineral extraction and processing operations, which are covered by ISO 24181-1.
