Witryna12 gru 2008 · The factors determining corrosion are reviewed in this paper, with an emphasis on iron tolerance limit and the production of high-purity castings. To understand the iron impurity tolerance limit, magnesium phase diagrams were calculated using the Pandat software package. WitrynaThe initial impurity requirements in plutonium were harder to meet than in the case of uranium, which had been employed as a testing and manufacturing process development surrogate. ... Then, during the following month, after the revised impurity tolerances did become available, it didn’t take someone (I don’t remember who) very long to ...
WitrynaSi was identified by TEM and XPS as a significant impurity, forming a blocking layer on the electrode surface. Full recovery of oxygen exchange kinetics on the measured samples was achieved after deposition of a La oxide film. Subsequent TEM studies indicate the formation of a porous La- and Si-containing film. WitrynaImpurity definition, the quality or state of being impure. See more.
