Abstract

Ferrotitanium ores and residues may vary widely in composition. Because of this, interelemerxt effects are very large. An X-ray spectrographic method will be described for the analysis of the light elements in these ores and residues. The method uses a standard helium path Norelco spectrograph with a tungsten target tube. A KAP analyzing crystal is used for all the elements investigated. Appropriate emission lines of the elements magnesium, aluminum, silicon, calcium, titanium, and iron are measured and the results are calculated on a small computer using the empirical corrections for interelernent effects of Lucas-Tooth and Pyne. The FORTRAN program for these calculations will be given.

The problems of sample preparation, standardization, interferences and instrumental variables will be discussed. A comparison of X-ray results with chemical analysis is made.

The method is especially adaptable to automated analysis and some of the systems needed will be outlined. The method may also be modified to analyze light elements in other matrices.
