Impurity tolerance
Witryna15 kwi 2024 · Fe impurity Corrosion tolerance limit Biocompatibility Degradation During the production of primary Mg using Pidgeon or Electrolysis methods, iron (Fe) is one of the most common impurities which can be introduced, leading to the formation of a Mg-based solid solution and/or Fe-containing intermetallic phases [1]. 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.
