Studies of porosity, connectivity, and parasitic phases in textured Bi-2212/Ag after non-melt heat treatments Conference Paper uri icon

abstract

  • Specimens of cold-pressed, highly textured Bi-2212 powders were subjected to sintering heat treatments to evaluate the impact of sintering upon texture, density, connectivity, microstructure, and growth of parasitic phases. A regime of non-melt sintering parameters were identified that produce near-solid density, strong texture, extensive growth of the Bi-2212 phase in the textured a-b planes, and no significant growth of parasitic phases. This favorable regime is stable over a sintering temperature range from 865°C - 875°C. The results establish one element of our strategy for fabrication of highperformance Bi-2212/Ag wire using textured powder in a 'jelly-roll' configuration. © 2012 American Institute of Physics.
