Optimization for preparing Bi 1.68 Pb 0.32 Sr 1.75 Ca 1.85 Cu 2.85 O 10+y powders by wet ball milling
Superconducting Bi 1.68 Pb 0.32 Sr 1.75 Ca 1.85 Cu 2.85 O 10+ y (Bi-2223) powders were prepared by a conventional solid-state reaction using hand grinding and wet ball milling. The effects of the ball milling and sintering times on the phase evolution were examined by x-ray diffraction and magnetic...
