【摘要】 通过掺杂Ag和PbO的方法降低YBaCuO的区熔温度到945℃以下,从而能够在金属Ag基底上进行区域熔炼,获得有织构的超导带材。掺杂的PbO与YBaCuO反应.生成了BaPbO₃。5wt%Ag+10wt%PbO的YBaCuO掺杂区熔样品所得结果较好,厚膜的J_c最大值为442A/cm²。更多还原

【Abstract】 The zone-melting temperature of YBaCuO tapes were decreased under 945□ by doping Ag and PbO in YBaCuO films, which made zone-melting process possible with Ag substrate not melted. From the XRD pattern of zone-melted sample, it was known that there was a reaction between YBa₂Cu₃O_7-δ and PbO, and the product was BaPbO₃. The result of YBaCuO films with 5wt%Ag and 10wt%PbO doped was better, whose J_c value was 442 A/cm².更多还原
