以柠檬酸和碱式碳酸镍为原料,采用溶胶-凝胶法制备柠檬酸镍前驱体纤维,在Ar气气氛下热分解得到金属镍纤维。通过FE-SEM/EDS、DSC-TG、XRD、FT-IR和XPS对金属镍纤维的形貌、前驱体的热分解过程及纤维的物相组成进行表征。结果表明柠檬酸镍前驱体纤维在300℃热处理时出现金属Ni,且热分解过程中没有氧化镍出现。故金属镍纤维是由前驱体直接热分解形成,不经过氧化镍热还原过程。
The nickel citrate precursor fibers were prepared,using citric acid and basic nickel carbonate as the raw materials by the sol-gel method.The nickel fibers were derived from thermal decomposition of the precursors in argon gas atmosphere.The morphologies,thermal decomposition process and structure of the nickel fibers were characterized by FE-SEM/EDS,DSC-TG,XRD,FT-IR and XPS,respectively.The experimental results indicated that the nickel appeared when the heat treatment temperature was 300℃,and there was no nickel oxide existed during the whole process of the thermal decomposition.So the nickel fibers could be formed directly by the thermal decomposition of the precursor fibers,without the process of nickel oxide reduction.
