报道了一种通过氧化物粉末装管法制备银包套Bi(Pb)-2223带材的新型前驱体粉末工艺。前驱体粉末由[此处缺失相关成分信息]和[此处缺失相关成分信息]的混合物制成。具有整体成分的完全加工带材显示出均匀的2223微观结构,仅含有少量第二相。在经过160小时的总反应时间以及两次中间压制后,对于一根[此处缺失厚度信息]厚的单丝带材,获得了(77 K,0 T)的临界电流密度。
A new precursor powder process for the fabrication of silver sheathed Bi(Pb)-2223 tapes by an oxide-powder-in-tube method is reported. The precursor powder is made from a mixture of and . Fully processed tapes with the overall composition showed an homogeneous 2223 microstructure containing only small amounts of second phases. A critical current density of (77 K, 0 T) was obtained for a thick single-filament tape after a total reaction time of 160 h with two intermediate pressings.
