Chemical analysis of aluminosilicate refractory products (alternative to the X-ray fluorescence method) - Part 2 : wet chemical analysis

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.

Chemical analysis of aluminosilicate refractory products (alternative to the X-ray fluorescence method) - Part 2 : wet chemical analysis

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.
