Description
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.
제1도는 Y-Ba-Cu-O계의 고온 초전도성 조성물의 상평형도이다. 제2도는 조성식이 YxBa2Cu3O7-y로 표현되는 고온 초전도성 조성물을 소결한 시편의 자유표면(free surface)의 광학 현미경 사진으로서, (a)도는 x=1.0 일때 사진이고, (b)도는 x=1.1일때 사진이다. 제3도는 제2도의 조성물을 1100℃에서 부분 용융하여 포정반응한 시편의 폴리싱된 표면(polished surface)의 광학 현미경 사진으로서, (a)도는 x=1.0 일때 사진이고, (b)도는 x=1.1일때 사진이다.1 is a phase diagram of a high-temperature superconducting composition of Y-Ba-Cu-O system. FIG. 2 is an optical micrograph of a free surface of a specimen obtained by sintering a high temperature superconducting composition whose composition formula is represented by YxBa 2 Cu 3 O 7 -y, (a) is a photograph when x = 1.0, and (b) Figure is a photograph when x = 1.1. FIG. 3 is an optical micrograph of the polished surface of the specimen prepared by partially melting the composition of FIG. 2 at 1100 ° C., (a) is a photograph when x = 1.0, and (b) is x = 1.1 When is a picture.
