Description / Abstract:

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 Na2O, SiO2, Fe2O 3, CaO, TiO2, P2O5, V2O 5, ZnO, MnO, Ga2O3, K2O, CuO, Cr2O3, and NiO on an un-dried sample basis.  The method is applicable to smelting-grade aluminium oxide.
