Abstract

The effects of graphene addition on the phase formation and superconducting properties of (BiPb)SrCaCuO (Bi-2223) ceramics synthesized using the co-precipitation method were systematically investigated. Series samples of Bi-2223 were added with different weight percentages ( = 0.0, 0.3, 0.5 and 1.0 wt.%) of graphene nanoparticles. The samples' phase formations and crystal structures were characterized via X-ray diffraction (XRD), while the superconducting critical temperatures, , were investigated using alternating current susceptibility (ACS). The XRD showed that a high- phase, Bi-2223, and a small low- phase, Bi-2212, dominated the samples. The volume fraction of the Bi-2223 phase increased for the sample with x = 0.3 wt.% and 0.5 wt.% of graphene and slightly reduced at x = 1.0 wt.%. The ACS showed that the onset critical temperature, , phase lock-in temperature, and coupling peak temperature, , decreased when graphene was added to the samples. The susceptibility-temperature (χ'-T) and (χ″-T) curves of each sample, where χ' and χ″ are the real and imaginary parts of the susceptibility, respectively, were obtained. The critical temperature of the pure sample was also measured.

摘要

系统研究了添加石墨烯对采用共沉淀法合成的(BiPb)SrCaCuO(Bi-2223)陶瓷的相形成和超导性能的影响。向系列Bi-2223样品中添加了不同重量百分比(=0.0、0.3、0.5和1.0 wt.%)的石墨烯纳米颗粒。通过X射线衍射(XRD)对样品的相形成和晶体结构进行了表征,同时使用交流磁化率(ACS)研究了超导临界温度 。XRD表明,样品中以高相Bi-2223和低相Bi-2212为主。对于添加了x = 0.3 wt.%和0.5 wt.%石墨烯的样品,Bi-2223相的体积分数增加,而在x = 1.0 wt.%时略有降低。ACS表明,向样品中添加石墨烯时,起始临界温度 、锁相温度 和耦合峰值温度 均降低。获得了每个样品的磁化率-温度(χ'-T)和(χ″-T)曲线,其中χ'和χ″分别是磁化率的实部和虚部。还测量了纯样品的临界温度。
