A
use of X-ray fluorescence relative intensities for analysis of metal alloys and
oxide materials
Abstract
An
X-ray fluorescence analysis technique is proposed, which is based on a use of
relative intensities. Calculations of x-ray fluorescence intensities being
performed to construct calibration curves, a number of necessary calibration
samples can be reduced. Standardless analysis can be performed, if necessary.
That parameters of calibration curves depend linearly on concentrations of
other elements simplifies accounting for their influence. To apply the approach
to analysis of samples containing significant amount of unmeasurable elements a
use of a dependence of a relation of Rayleigh-to-Compton scattering peaks on a
total content of these elements is suggested. The technique’s validity was
shown by analysis of standard steel samples, metal cuttings and iron-ore raw
materials.
Key words: X-ray fluorescence analysis, relative X-ray intensities, metal alloys,
oxide materials.
