摘要: Abstract The high-temperature superconducting phase of the Bi-2223 system, with and without Pb, was prepared by sol-gel method. material characterized X-ray powder diffraction magnetization. An almost pure obtained on addition Pb(NO 3 ) 2 (0.2 m in substitution for Bi less time sintering needed.
