BS EN ISO 21079-1-2008 包含氧化铝、氧化锆和硅石的耐火材料的化学分析.包含5%~45%ZrO2的耐火材料(可选择X射线荧光法).仪器、试剂和分解
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 (ISO 21079-1:2008)
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.
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.
