This part of ISO21079 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 Table1. Table1 Range of determination (%by mass) Component Range Component Range LOI –1 to 40 MgO 0,01 to 2 SiO2 0,1 to 45 Na2O 0,01 to 3 Al2O3 1 to 80 K2O 0,01 to 1 Fe2O3 0,01 to 2 Cr2O3 0,01 to 3 TiO2 0,01 to 5 ZrO2 5 to 45 CaO 0,01 to 2 HfO2 0,01 to 2 NOTE The values other than LOI are on an ignited basis. This part of ISO21079 is not applicable to MgO-based refractories. NOTE This part of ISO21079 gives alternatives to the X-ray fluorescence (XRF) method given in ISO12677.
