Abstract

Aluminum, is determined within the range 2-16% in iron. Repeatability of X-ray determinations is within a standard deviation of 0.07 % aluminum for a sample containing 10.2% aluminum. The standard deviation of the chemical values from the straight line calibration curve is 0.3% aluminum. X-ray analytical time is approximately 5% of the time required for chemical analysis. Peak-to-background ratio is improved by using a chromium-target thin-window X-ray tube instead of a tungsten tube.
