Y. Takao et al., PREPARATION AND PROPERTIES OF BA2YCU3O7-X-BAZRO3 SUPERCONDUCTIVE COMPOSITE BY SPRAY-DRYING METHOD, Nippon Seramikkusu Kyokai gakujutsu ronbunshi, 102(3), 1994, pp. 237-240
Ba2YCu3O7-x-BaZrO3 superconductive composite was prepared by spray dry
ing method. The composite sintered body had nano-composite structure c
onsisting of Ba2yCu3O7-x and intragrain BaZrO3 particles with a less t
han 100 nm size. The contribution of BaZrO3 particles to flux pinning
was discussed by microstructure observation and pinning property measu
rement of the sintered body.
