Gd2 (Ba4-rSrr) CuZrOy nano-powder and manufacturing method thereof, and single-domain gadolinium barium copper oxide bulk superconductor and manufacturing method thereof
The invention provides a Gd2 (Ba4-rSrr) CuZrOy nano-powder and a method for improving the performance of a single-domain gadolinium barium copper oxide superconducting block by using the Gd2 (Ba4-rSrr) CuZrOy nano-powder, and the nano-powder comprises the following components by mole ratio: 1 mole of Gd2O3, 0-4 moles of BaCO3, 0-4 moles of SrCO3, 1 mole of CuO and 1 mole of ZrO2, the chemical formula of the nano powder is Gd2 (Ba4-rSrr) CuZrOy, r is larger than or equal to 0 and smaller than or equal to 4, and y is the oxygen content in the Gd2 (Ba4-rSrr) CuZrOy powder. The Gd2 (Ba4-rSrr) CuZrOy (r = 0, 1, 2, 3, 4) nano-powder with good chemical stability and the complete preparation method of the Gd2 (Ba4-rSrr) CuZrOy (r = 0, 1, 2, 3, 4) nano-powder are invented by a method for replacing Ba in RE2Ba4CuMOy (M = U, Mo, Zr, Bi, Nb, W,...) phase with Sr, and the magnetic flux pinning capacity and the superconducting performance of a GdBCO superconducting block are improved by doping the Gd2 (Ba4-rSrr) CuZrOy nano-particles.
本发明提供了一种Gd2(Ba4‑rSrr)CuZrOy纳米粉体及用其提高单畴钆钡铜氧超导块材性能的方法,其中，该纳米粉体，以100摩尔计，按摩尔数配比是：1摩尔的Gd2O3，0摩尔～4摩尔的BaCO3，0摩尔～4摩尔的SrCO3，1摩尔的CuO，1摩尔的ZrO2；该纳米粉体的化学式为Gd2(Ba4‑rSrr)CuZrOy，其中r的取值范围是0≤r≤4，y是在Gd2(Ba4‑rSrr)CuZrOy粉体中的含氧量；本发明通过用Sr元素替代RE2Ba4CuMOy(M＝U,Mo,Zr,Bi,Nb,W,…)相中Ba元素的方法，发明了一种化学稳定性很好的Gd2(Ba4‑rSrr)CuZrOy(r＝0，1，2，3，4)纳米粉体及其完整的制备方法，通过Gd2(Ba4‑rSrr)CuZrOy纳米颗粒掺杂、提高了GdBCO超导块材磁通钉扎能力和超导性能。
