Ni-Co固溶体合金价电子结构分析--Co在合金中作用的初步探讨李博东北工学院应用物理教研室摘 要:本文应用经验电子理论,对工业范围内(Co含量<25％)的Ni-Co固溶体合金的价电子结构进行计算,给出了价电子结构分布参数(键共价电子对数,共价电子总数,晶格电子总数).计算的理论键距,理论磁距与实验值符合得很好.本文还初步探讨了Ni基高温合金中加Co的微观本质.为进一步研究合金的宏观物理,化学性质提供了微观资料.关键词:价电子结构;键距;磁矩;......
410083, China) Abstract: A novel process was developed to treat the high-aluminum limonite ores. Al-Fe separation from a high-aluminum limonite ore with total iron grade of 48.92% and Al2O3 content of 8.16% (mass fraction) was studied by reduction roasting with addition of sodium salt followed by magnetic-separation. The results show that metallic iron powder with total iron grade of 91.00......

Solvent impregnated resin prepared using task-specific ionic liquids for rare earth separation CHEN Ji1,MA Jiutong2,JI Yang1,SUN Xiaoqi1 (1.State Key Laboratory of Rare Earth Resource Utilization...) was studied for rare earth (RE) separation. Adsorption ability of the SIR was indicated to be obviously higher than that prepared by [A336][NO_3] because of the functional anion of [A336][CA-100]. Adsorption......
