Iron and titanium, the major constituents in iron ores, were X-ray spectrometrically determined by using the dilution parameter method. A standard and samples possessing a similar composition were diluted with the diluent ZrO2 to their proper respective ratios. After measuring the intensity of the fluorescent X-ray, the dilution parameter was calculated from the following equation. Pa = {{Ias/(Ias)d － 1} / {D － 1}} The dilution parameters were used to correct the difference between the matrix effect of the standard and that of the sample. The content of the major constituents was calculated, without using any standard calibration curves, from the following equation; Wa = Wa*·{Ias / Ias*}·{Pa* / Pa} where asterisks indicate the standard. The results agreed with those of the wet analysis within 2% of relative error, and the precision of the experiment was also tolerably good.
