X-ray Fluorescence Spectrometry Determination of Chromite by Powder Briquette Pressed Technique

摘要

A rapid analysis method of determination of six components of chromite was set up by x-ray fluorescence spectrometry using powder-briquetting technique and adopting theoretical alpha coefficient correcting matrix effects. The grains-size effect was eliminated by means of sample-making technique parameters optimization and the mineral effect was counteracted by standard curve from criterion samples made artificially. The analysis results of Cr_2O_3, TFe, SiO_2, MgO, Al_2O_3 and CaO in chromite samples show that both precision and accuracy dose not lower than that of chemical method.
