Chemical analysis of aluminosilicate refractory products (alternative to the X-ray fluorescence method) -- Part 3: Inductively coupled plasma and atomic absorption spectrometry methods
This part of ISO 21587 specifies inductively coupled plasma/atomic emission (ICP/AE) spectrometry and flame atomic absorption (FAA) spectrometry methods for the chemical analysis of aluminosilicate refractory products and raw materials. The methods are applicable to the determination of the following: — silicon(IV) oxide (SiO2) — aluminium oxide (Al2O3) — iron(III) oxide (total iron oxide calculated as Fe2O3) — titanium(IV) oxide (TiO2) — manganese(II) oxide (MnO) — calcium oxide (CaO) — magnesium oxide (MgO) — sodium oxide (Na2O) — potassium oxide (K2O) — chromium(III) oxide (Cr2O3) — zirconium oxide (ZrO2) — phosphorous(V) oxide (P2O5) This part of ISO 21587 gives alternatives to the X-ray flluorescence (XRF) method given in ISO 12677:2003, Chemical analysis of refractory products by XRF — Fused cast bead method.
