Abstract
Superconductor precursor powder was ground in a planetary mill using various combinations of grinding container, balls and carrier (dry and wet). Dry milling was found to be more effective than wet milling for reducing particle size irrespective of container and ball materials used. Serious Si contamination was observed in powders milled using agate grinding material. Some C from polypropylene container was found after milling, but no Zr from YSZ balls. Effect of powder particle size, initial packing density and various powder preparation techniques on the properties of Bi2223/Ag tapes was systematically investigated in terms of high-Tc phase formation, microstructure and critical current density (Jc).
