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) - Flame atomic absorption spectrophotometry (FAAS) and…1 Scope This part of ISO 21079 specifies flame atomic absorption spectrophotometry (FAAS) and inductively coupled plasma emission spectrometry (ICP AES) methods for the analysis of AZS (alumina, zirconia, and silica) refractory products (containing 5 % to 45 % of ZrO2) and raw materials. This part of ISO 21079 is not applicable to MgO based refractories. This part of ISO 21079 gives alternatives to the X ray fluorescence (XRF) method given in ISO
