Synthesis and characterization of Ln-123 superconductors

摘要

A sol-gel method was applied to prepare precursors for NdBa_2Cu_3O_(7-x) (Nd-123) and SmBa_2Cu_3O_(7-x) (Sm-123) superconducting compounds. The sintered products were examined by X-ray diffraction analysis (XRD) and scanning electron microscopy (SEM). The
