THE SPECTROGRAPHIC DETERMINATION OF CALCIUM AND ZIRCONIUM IN BISMUTH- URANIUM ALLOYS

Technical Report ·
OSTI ID:4327713
Bismuth alloys were converted to oxides, lanthanum was incorporated as an internal standard, and 5 mg charges were cemented to copper electrodes by means of a thermosetting resin. Samples were excited by a triggered uni- directional discharge, and the spectra were evaluated by microphotometry. The effective concentration range for both elements was 50 to 500 ppm. Coefficients of variation for single spectra were 5% for zirconium and 8.5% for calcium at the 300 ppm level. (auth)
