Preparation of Bi-Pb-Ca-Sr-Cu-O superconducting thick films using spray-pyrolyzed fine powders

High- T c superconducting thick films were prepared using fine powders obtained by spray pyrolysis. The 110 K phase was predominantly formed in the films heat-treated at 855°C. The films prepared using fine powders with an average particle size of 1.4 µm showed a higher T c (zero) of 105 K compared...

Zusammenfassung:	High- T c superconducting thick films were prepared using fine powders obtained by spray pyrolysis. The 110 K phase was predominantly formed in the films heat-treated at 855°C. The films prepared using fine powders with an average particle size of 1.4 µm showed a higher T c (zero) of 105 K compared with those using powders of 0.8 µm.
