Scope: This International Standard sets out a wavelength dispersive X-ray fluorescence spectrometric method for the analysis of aluminium oxide for trace amounts of any or all of the following elements: sodium, silicon, iron, calcium, titanium, phosphorus, vanadium, zinc, manganese, gallium, potassium, copper, chromium and nickel. These elements are expressed as the oxides Na 2 O, SiO 2 , Fe 2 O 3 , CaO, TiO 2 , P 2 O 5 , V2 O 5 , ZnO, MnO, Ga 2 O 3 , K 2 O, CuO, Cr2 O 3 , and NiO on an un-dried sample basis. The method is applicable to smelting-grade aluminium oxide. The concentration range covered for each of the components is given in Table 1 . Table 1 — Applicable concentration range Concentration range % Component Na 2 O 0,10 to 1 ,00 SiO 20,003 to 0,05 Fe 2 O 30,003 to 0,05 CaO 0,003 to 0,10 TiO 20,0005 to 0,010 P2 O50,0005 to 0,050 V2 O 50,0005 to 0,010 ZnO 0,0005 to 0,010 MnO 0,0005 to 0,010 Ga 2 O 30,0005 to 0,020 K2O 0,0005 to 0,010 CuO 0,0005 to 0,010 Cr2 O 30,0005 to 0,010 NiO 0,0005 to 0,010
