Trans. Nonferrous Met. Soc. China 26(2016) 1055-1062 Thermodynamic assessment of Ni-Yb binary system Dai-man ZHU1, Chang-rong LI1, Cui-ping GUO1, Zhen-min DU1, Jun-qin LI2 1. School of Materials...-Yb binary system was carried out using the CALPHAD (calculation of phase diagrams) method. The liquid phase is modeled as the associate model with the constituent species Ni, Yb and YbNi3, owing......
氟化物介质熔盐电解制备Ni-Yb合金及其表征王旭,廖春发,王瑞祥,孙强超江西理工大学冶金与化学工程学院摘 要:采用LiF-CaF2介质和Yb2O3原料的氟盐-氧化物体系电解制得了Ni-Yb合金.通过循环伏安法分析了Yb(Ⅲ)离子的电化学行为,利用X射线衍射仪(XRD),扫描电子显微镜(SEM)及能谱仪(EDS)表征并分析了电解产物的成分及物相组成.结果表明,在LiF-CaF2(n(LiF)∶n(CaF2)=77∶23)的体系中,温度为1 523 K,槽电压4.0 V,以金属Ni为自耗阴极,经3 h电解能成功制备出Ni-Yb合金.Yb(Ⅲ)离子的还原分两步进行,首先Yb(Ⅲ)得到一个电子,被还原为Yb(Ⅱ)离子,随后Yb(Ⅱ)离子在Ni阴极表面继续被还原为Yb并被合金化,最终形成基本组成相为......
