Abstract
To better understand what effects solutes have on the true intrinsic properties of zirconium, it is imperative to first prepare metal of extreme purity. This is of particular importance in their present studies concerning the effects of irradiation on the properties of creep and growth in zirconium. One of the most effective methods of preparing high purity metals is by electrotransport processing at high temperatures. In 1940, DeBoer and Fast reported that oxygen migrated toward the anode in zirconium when a dc current is passed through it at elevated temperatures. This was further substantiated by Claudson. Schmidt et al. measured the electric mobility, diffusivity and effect valence of carbon, nitrogen and oxygen in beta zirconium over the temperature range of 1900 K to 2075 K. It was the purpose of this study to utilize these previously determined electrotransport parameters and high vacuum technology to prepare a small amount of ultrapure zirconium for use in irradiation studies at the Chalk River Nuclear Laboratories.
