Textured Bi2Sr2Ca2Cu3O10+y tiles manufactured from sintered and plasma-sprayed precursors for magnetic shieldingtiles manufactured from sintered and plasma-sprayed precursors for magnetic shielding

Superconducting magnetic shields have potential weight advantages over conventional materials as efficient, light, shielding materials. Shielding properties in high fields depend on many material features, including alignment, critical current densities, and flux pinning. Diffusion texturing can produce grain alignment with the c-axis parallel to the sheet plane. In this article, the superconducting tile is made by bonding the ceramic precursor, SrCaCu₂, to a metal substrate before texture growth with Pb-Bi-O. The bonding can be produced by sintering or by plasma spraying. After diffusion texture growth, a tile with a superconducting transition temperature of 110 K and a critical current density greater than 2500 A/cm² has been manufactured and characterized.
