A procedure is described for the quantitative spectrographic estimation of Hf/Zr and Zr/Hf ratios in binary oxide mixtures using the intermittent a-c arc excitation technique. Five selected line pairs cover the range 0.03to 64% Hf/Zr and 0.1 to 90% Zr/Hf (wt/wt). The method was applied to the analysis of hafnia in a sample of Travancore zircon and the minor constituent in a large number of binary oxide fractions obtained in a scheme of chromatographic separation of zirconium from hafnium.
