| Abstract |
We have obtained a dense and unidirectionally solidified Bi-Pb-Sr-Ca-Cu-O superconductor thick film by line heating. When the maximum line heating temperature was above 870℃, it was divided into a (001) textured l0K phase and a Bi free phase solidified in scanning direction. After post heat treatment at 860℃ for 12h, it became a dense and homogenious superconductor(Tc=65K) by diffusion between two phases. |
