Abstract
ISO 12677-2:2007 specifies traditional ("wet") 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 12677 gives alternatives to the X-ray fluorescence (XRF) method given in ISO 12677:2003.
