Abstract
Superconducting Bi1.6Pb0.4Sr2Ca2Cu3O7 was prepared by a solid-state reaction using high-energy milling for the starting materials. The effects of the sintering temperature and time on the phase evolution, microstructure, and superconducting properties were examined by thermogravimetric analysis, X-ray diffraction, scanning electron microscopy, and four-point probe resistivity measurements. High-energy milling decreased the precursor particle size to approximately 30 nm with a relatively uniform distribution of multi-compositions. Because of the mechanochemical activation for the starting materials, the reaction temperature was decreased to 750 degrees C due to the decreased diffusion length required for the solid-state reaction. Bi1.6Pb0.4Sr2Ca2Cu3O7 prepared by high-energy milling showed good superconducting properties with T-c similar to 100 K, which is superior to the same material prepared by ball milling and sol-gel routes.
