✦ Synopsis

We report the constitution, characterization and superconducting temperatures of high-temperature superconducting Y-A-Cu-B (A: Sr, Ba; B: O, C1, F). Novel high-T c superconductors like La2Cul.xAgxO 4 but also without any rare earths like Sr2Bi2Cu207 and Sr-Bi-Ca-Cu-O have been also investigated. High-T superconductivity with T onsets up to 120 K (midpoint: 115 K, zero resistivity 79 K) is observed in SrBiCaCu20 ~_+x (0 -< x -< 1).

High-temperature superconducting particles of the 1:2:3 yttrium-barium-copper oxide systems were synthesized in an inverted configuration coannular diffusion flame. The particles were produced from a spray pyrolysis technique, employing aerosolized nitrate salts of Y, Ba, and Cu. The product showed
