Fabrication of BSCCO Nanocrystal SuperconductorsCheng ZHANG Xin WANG Yongzhong WANG Guiwen QIAO Institute of Metal Research,Academia Sinica,Shenyang,110015,China摘 要:<正> Nanocrystal materials have their special properties because of very small grain size.Nanocrystalsuperconductors were prepared by crystallizing the amorphous slices with nominal......
TEM Analysis on YBCO Composited Superconducting Tapes朱心昆,赵昌森,王瑞坤,黄一兵,邓凤翔摘 要:<正> The microstructures of the YBCO composited superconducting tapes with different Jc were analysed byTEM.The relationship between microstructure and Jc of the tapes is discussed in detail.It is demonstrated thatJc value of the tapes increases significantly......
="ChDivSummary" name="ChDivSummary">To reduce the production cost of Bi-2223 superconducting tapes, Bi-2223/Ag/Ni tapes were fabricated by the powder-in-tube process. The effect of heat treatment on the microstructure and critical current of the Bi-2223/Ag/Ni tapes were studied. The phase compositions of the samples were characterized using XRD. The microstructure was observed using SEM......
BSCCO超导体中均匀排布ZnO缺陷的纳米复合制备 赵晓鹏1,许战立1,陈政1,姜万涛1 (1.西北工业大学,电流变技术研究所,陕西,西安,710072) 摘要:通过纳米复合掺杂的方法,在BSCCO超导体中引入了均匀排布的纳米ZnO缺陷.研究并比较了不同掺杂方法对超导体性能以及ZnO在超导体中分布状态的影响.测试结果表明,不同掺杂方法所制备的样品均有明显的超导现象;经HRSEM表征,纳米复合掺杂所得样品中ZnO缺陷呈线状均匀排布,粒径约为100 nm. 关键词:超导; 纳米复合; 掺杂; BSCCO; ZnO; [全文内容正在添加中] ......
