Abstract
A rapid x-ray fluorescence method has been developed for analysis of chrome ores, chrome-magnesia, and magnesia-chrome materials by fusion of the powdered samples with sodium hexametaphosphate and lanthanum oxide. Three NBS standards, one British standard and a few in-house wet chemically analyzed samples were run for SiO2, Fe2O3, Al2O3, CaO, MgO, and Cr2O3 for standardizing the method. Linear regression equations were applied for determining the best fit line. Relative standard deviations were 3% or less except for CaO (5.4%) because of its usually very low concentration.
