DIN EN ISO 21079-1-2008 含有氧化铝、氧化锆和硅石的耐火材料的化学分析.含有5%~45%ZrO2的耐火材料(可选择X射线荧光法).第1部分:仪器、试剂和分解
Chemical analysis of refractories containing alumina, zirconia and silica - Refractories containing 5 % to 45 % of ZrO2 (alternative to the X-ray fluorescence method) - Part 1: Apparatus, reagents and dissolution (ISO 21079-1:2008); German versio
This part of ISO 21079 specifies methods for the chemical analysis of AZS (alumina, zirconia, and silica)
refractory products (containing 5 % to 45 % of ZrO2) 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.
The range of determination is given in Table 1.
Table I -- Range of determination (% by mass)
This part of ISO 21079 is not applicable to MgO-based refractories.
NOTE This part of ISO 21079 gives alternatives to the X-ray fluorescence (XRF) method given in ISO 12677.
