Abstract

The aim of the work was to study the resistance of Bi/Pb superconducting ceramics produced by solar energy, of the firing temperature and time. Based on the analysis of superconducting materials synthesis known technologies, solar technology as a non-trivial way to obtain superconductors with high pinning is proposed. The influence of the solar spectrum and the temperature gradient, as the main factors of solar technology, aimed the superconducting properties improving is substantiated. The relationship between the crystallite nuclei lamellar structure and superconducting ceramics morphology is shown. The dependence of the of Bi/Pb ceramics resistance in the temperature range 80-320 K has been studied. Anomalies of resistance in the temperature range of 250-320 K were revealed.
