Abstract

This paper covers a new insight into high temperature Tb2O3-ZrO2 insulation coatings on Ag substrate for magnet technologies. Sol-gel methods used to produce Tb2O3-ZrO2 insulation layers are described, emphazing key parameters. The thermal, structural, microstructural, and electrical properties of Tb2O3-ZrO2 coatings on Ag metallic tape substrates were discussed in our research. It was found that commercial Ag and AgMg sheathed Bi-2212-long-length tapes would be insulated with pure ZrO2 and Tb2O3-ZrO2 coatings and then the coated tapes could be wound to fabricate an electromagnet.
