The purpose was to investigate the compatibility of thick-film, high-temperature superconductors with multilayered ceramic (MLC) packages for cryogenic applications. Paste consisting of standard organics and YBCO powder of -325 mesh particle size was screen-printed onto Dupont 951 Green Tape. The system was cofired at temperatures ranging from 925°C to 975°C. The quality of the cofired system was characterized in several ways: Meissner diamagnetism, scanning electron microscopy, x-ray diffraction, and AC susceptibility tests were performed to determine the superconducting capability of the system. Samples cofired at 950°C retained some superconductivity after firing and showed the best compromise be­tween sintering and degradation.5 pages257.31 KBapplication/pdfapplication/zipenIn CopyrightMaterials ScienceProcessing of YBO Thick FilmsMultilayered ElectronicsArticleVirginia Tech Department of Materials Science and Engineeringhttps://doi.org/10.21061/jumr.v1i0.1548112578-9570
