本文件规定了用作精细陶瓷原料的氧化锆粉末的化学分析方法。 规定了精细陶瓷用氧化锆粉末中锆、铝、钡、钙、铈、钴、钆、铪、铁、镁、钾、硅、钠、锶、钛、钇含量的测定方法。试样通过酸压分解或碱熔分解。锆和钇的含量通过沉淀和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法测定铝、钡、钙、铈、钴、钆、铪、铁、镁、钾、硅、钠、锶和钛的含量。

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.
