APPLICATION OF X-RAY DIFFRACTION ANALYSIS TO URANIUM CERAMICS .2. QUANTITATIVE ANALYSIS OF URANIUM CARBIDES

Different X-ray diffractometer methods are proposed for the determination of uranium carbides in binary and multicomponent mixtures (direct methods, internal standard and active dilution method). The relative standard deviation was found to be 2%. Limits of detection for UC2 and UO2 in UC were about 0.04%. Calculations showed that the UC2 in the samples used contained 9.00 and 9.28±0.04 wt% of combined carbon, corresponding to UC1.96±0.01 and UC2.03±0.01. © 1968.
