Noudem] Using a combination of standard ceramic processing and an infiltration technique, single-grain superconductor foams and with multiple holes of YBa2Cu3Oy (Y123) have been produced. The process, involving negligible shrinkage, results in an improved microstructure with a uniform distribution of submicron Y2Ba1Cu1O5 (Y211) inclusions in the Y123 matrix. The foam or artificially patterned holes structure could be highly favorable for good oxygenation, better cooling and consequently for an efficient heat extraction from the superconducting element in view to overcome the typical hot-spot phenomena commonly observed in superconducting fault current limiters. In this work, the processing conditions and the magneto-transport measurements of these foams are reported. The investigations reveal the superconducting properties to be similar to those of bulk melt processed materials. The magnetic hysteresis vs. field measurements show a high anisotropy of the critical current density in good agreement with the microstructural observations. The advantages of the infiltration growth process and of the novel porous superconductor (Y123) ceramic are discussed.
