概要
- 論文の詳細を見る
The high-T_c YBa_2Cu_3O_<7-x> (123) superconductor has been synthesized through a decomposition of organic acid salts. T_c's of 92 K have been obtained after a relatively short sintering in the 123 specimen. Effects of silver addition and zirconium substitution on superconducting properties and structures were studied. The Ag addition and the Zr substitution appreciably enhances the J_c of sintered 123 specimen. The Ag addition decreases the optimum sintering temperature by about 50℃. The Zr substitution is found to significantly change the morphology of 123 grains.
