Growth structure and superconductivity of Bi$_{1.7}$Bi$_{0.3}$Sr$_{2}$Ca$_{2}$Cu$_{3}$O$_{10+\delta }$ ceramics synthesized from glass-crystal precursors processed in solar type ovens

The growth structure as well as the superconductivity of Bi/Pb2223 alloys is reported. Periodic lattice distortions (PLD) along the ab plane diagonal, direction of superconducting transport at the transition temperature, $T_{c}$=107K are found to dominate the growth. Trransport induced by the PLD may be responsible for the sharp T$_{c}$ transitions, and the bursts of frequency and Abrikosov oscillations observed above the transition temperature up to 150K. Chemical synthesis in a heliostat oven was followed by fast quenching of the melt and annealing at 840-850K, XRD near the Cu K-edge, and T$_{c}$ measured by axial-torsional vibrations in transverse magnetic fields. T$_{c}$ and phaase purity obtained by green solid state chemistry, in a solar spectrum, will be discussed.
