标准摘要
[中文适用范围]： ISO 21079 的这一部分规定了使用传统（“湿法”）方法、电感耦合等离子体原子发射 (ICP-AE) 光谱法和火焰原子吸收 (FAA) 光谱法对 AZS（氧化铝、氧化锆和二氧化硅）耐火产品（含有 5% 至 45% 的 ZrO2）和原材料进行化学分析的方法。它涵盖了仪器、试剂和溶解方法。ISO 21079 的这一部分不适用于 MgO 基耐火材料。 [外文原描述]： ISO 21079-1:2008 specifies methods for the chemical analysis of AZS (alumina, zirconia, and silica) refractory products (containing 5 % to 45 % of ZrO 2 ) and raw materials, using traditional ("wet") methods, inductively coupled plasma atomic emission (ICP-AE) spectrometry and flame atomic absorption (FAA) spectrometry. It covers apparatus, reagents and dissolution methods. ISO 21079-1:2008 is not applicable to MgO-based refractories. ISO 21079-1:2008 gives alternatives to the X-ray fluorescence (XRF) method given in ISO 12677.
英文名称Chemical analysis of refractories containing alumina, zirconia and silica — Refractories containing 5 percent to 45 percent of ZrO2 (alternative to the X-ray fluorescence method) — Part 1: Apparatus, reagents and dissolution
