Keywords:
AFM, sold state, ceramic, bismuth, Superconducting, nano size, critical temperatureAbstract
The research focuses on the effects observed in the superconducting material resulting from the annealing of Bi₂Sr₂Ca₃Cu₄O₁₀₊δ samples at varying temperatures, starting at 650 °C and increasing by 100 °C on three occasions; that is, in the second case the temperature reaches 750 °C and in the third it reaches 850 °C. In each case, we record the changes in the structure of the material used, as well as their effect on conductivity. The material was prepared in vitro using the solid-state method and synthesised nanoscale. The material was calcined in an oxygen atmosphere to control the phase growth and the structure of the . The results of the X-ray diffraction analysis showed a sequential transition from low-order layers to a well-developed phase, Similarly, the results of the electrical testing showed a marked improvement in conductivity at elevated temperatures, whilst atomic force microscopy (AFM) scans revealed good interparticle bonding within the nanomaterial, The rough surface and distinctive structural morphology at high temperatures demonstrated that the optimum temperature for achieving a superconducting application is 850 °C in the bismuth compound used.
