The basic theory and methods of X-ray fluorescence are briefly discussed. Pure synthetic mullite was made by mixing aluminum and silicon chlorides in non-aqueous solvent, coprecipitating as hydroxides, calcining to remove solvents and firing to 1600°C. Additions of Fe2O3, TiO2 and Cr2O3 to the high purity mullite were used to produce standard calibration curves for use in the analysis of unknowns. Experimental techniques are described and standard curves are presented. The method is rapid and results are comparable in accuracy to those of wet chemical analysis.
