精细陶瓷（高级陶瓷、高级工业陶瓷）氧化锆粉末化学分析方法

[中文适用范围]： 本标准规定了精细陶瓷原料氧化锆粉末的化学分析方法。 本标准规定了精细陶瓷用氧化锆粉中锆、铝、钡、钙、铈、钴、钆、铪、铁、镁、钾、硅、钠、锶、钛、钇含量的测定方法。 测试样品因酸压分解或碱熔而分解。 锆和钇的含量通过沉淀重量分析法或电感耦合等离子体发射光谱法（ICP-OES）测定。 采用 ICP-OES 方法测定铝、钡、钙、铈、钴、钆、铪、铁、镁、钾、硅、钠、锶和钛的含量。 [外文原描述]： This document specifies methods for the chemical analysis of zirconium oxide powders used as the raw material for fine ceramics. It stipulates the determination methods of the zirconium, aluminium, barium, calcium, cerium, cobalt, gadolinium, hafnium, iron, magnesium, potassium, silicon, sodium, strontium, titanium and yttrium contents in zirconium oxide powders for fine ceramics. The test sample is decomposed by acid pressure decomposition or alkali fusion. Contents of zirconium and yttrium are determined by using either a precipitation and gravimetric method or an inductively coupled plasma–optical emission spectrometry (ICP–OES) method. Contents of aluminium, barium, calcium, cerium, cobalt, gadolinium, hafnium, iron, magnesium, potassium, silicon, sodium, strontium and titanium are determined by using an ICP–OES method.
