| Electrical and mechanical properties of the Bi2-xKxPb0.3Sr2Ca2Cu3Oy superconductors for 0≤x≤0.5 was investigated using the dc electrical resistivity and static Vickers hardness tests. The results show improvements in the superconducting and deterioration of the mechanical properties with increasing the substitution, as confirmed by X-ray diffraction and scanning electron microscope investigations. |
