Abstract

A method for the quantitative spectrographic analysis of the materials used in oxide coated thermionic cathodes for Fe, Cu, Pb, Mg, Mn, and Al is described. The materials consist of barium-strontium carbonate or barium-strontium-calcium carbonate. The basic raw materials consist of barium nitrate, strontium nitrate, and calcium nitrate. The method employs briquetted samples and a high voltage alternating current arc. Fifteen samples can each be analyzed for six elements in two hours with an elapsed time of eighty seconds per determination.
