Abstract

The platinum flux technique, well established for the determination of oxygen in titanium, was successfully applied to the analysis of zirconium for its oxygen content after a systematic study of the optimum experimental conditions. The extraction of oxygen was complete in 20 min in the temperature range of 1850 to 2100° with a ratio of flux to sample of about 4.5:1 to 8:1. Statistical analysis of the results on a homogeneous sample gave a standard deviation of 0.0038 weight % and a coefficient of variance of 2.9%atalevelof 0.131 weight % of oxygen in zirconium. The recommended experimental conditions are a 0.1-g sample, a 5:1 flux-to-sample ratio, and 20 min extraction at 1900°–1950°.
