Method of simultaneous synthesize for Y123 and Y211 and fabrication of YBCO single crystal
Y123와 Y211분말의 동시 합성과 YBCO 초전도 단결정 제조
Abstract
A common YBCO powder has been made from a mixture of Y123 and Y211 that heated at different temperatures, respectively. The synthesis temperature of Y211 is lower than Y123. If Y211 has been heated as a synthesis temperature of Y123, a particle size of it may be very coarse. It exist as one of main defects for superconductor. But We simultaneously synthesize a YBCO(its composition is (Y123+0.4Y211)+
