Chemical analysis of ferrous Materials. Analysis of ferro-silicon. Determination of Si and Al by X-ray fluorescence spectrometry1 Scope This Technical Report describes a X ray fluorescence (XRF) spectrometric method for the determination of Si and Al contents in ferro silicon materials. The method is applicable to: Si contents between 40 % and 90 %; Al contents between 0,5 % and 6 %. The correction of the spectrometric measurement from spectral interferences on the analytical lines used is essential. This Technical Report is valid for the analytical lines: Si K 7. 126 (for
