Reveal of relationship between microscopy architecture and mechanical performance of Y/Bi substituted Bi-2212 engineering ceramics.

This study aims to find out how the crystallinity quality, surface morphology, and mechanical performances change with the substitution of yttrium (Y) for bismuth (Bi) impurity within molar ratios of 0.00 ≤ x ≤ 0.12 in the BiYSrCaCuO (Bi-2212) cuprates to reveal the dependence of micro surface topology on the substitution mechanism and achieve a strong relation between the impurity ions and crystallization mechanism.

Support of polaronic states and charge carrier concentrations of YBaCuO ceramics by oxygen and MnO impurity.

The influence of oxygen and MnO impurity addition intervals 0.01 ≤ x ≤ 0.30 on the basic electrical conductivity, stabilization, crystallinity quality, grain boundary couplings, structural, orbital hybridization mechanisms, and superconducting properties of YBaCuOMn ceramics has extensively been analyzed by electrical resistivity, X-ray diffraction investigations, and related theoretical results.
