Abstract
Official abstract text for this publication.
The present invention provides a nickel nanowire, which is resistant to break by stress. The present invention relates to a nickel nanowire having a face-centered cubic lattice structure and a crystallite size in a direction of a (111) lattice plane of 10 nm or less.
First claim
Opening claim text (preview).
The invention claimed is: 1 . A nickel nanowire having a face-centered cubic lattice structure and a crystallite size in a direction of a (111) lattice plane of 10 nm or less, and having a saturation magnetization of 20 emu/g or more. 2 . The nickel nanowire according to claim 1 , wherein the crystallite size in the direction of the (111) lattice plane is larger than a crystallite size in a direction of a (110) lattice plane. 3 . The nickel nanowire according to claim 2 , wherein the crystallite size in the direction of the (110) lattice plane is larger than a crystallite size in a direction of a (100) lattice plane. 4 . The nickel nanowire according to claim 1 , having an average diameter of 50 nm or more and less than 1 μm. 5 . The nickel nanowire according to claim 1 , having an average length of 5 μm or more. 6 . The nickel nanowire according to claim 1 , wherein the crystallite size in the direction of the (111) lattice plane is 1 to 8 nm. 7 . A dispersion comprising the nickel nanowire according to claim 1 . 8 . A molded article comprising the nickel nanowire according to claim 1 . 9 . A method for producing a nickel nanowire, comprising a step of reducing two or more nickel salts having different dissociation constants and/or counter ions in a reaction solution while applying a magnetic field to obtain the nickel nanowire according to claim 1 . 10 . The method for producing a nickel nanowire according to claim 9 , wherein the two or more nickel salts comprise nickel chloride and nickel sulfate salts, and a proportion of the nickel chloride to a total of the nickel chloride and the nickel sulfate salts is 70 to 98 mol %. 11 . The method for producing a nickel nanowire according to claim 9 , wherein the two or more nickel salts comprise nickel chloride and nickel acetate salts, and a proportion of the nickel chloride to a total of the nickel chloride and the nickel acetate salts is 70 to 98 mol %. 12 . The method for producing a nickel nanowire according to claim 9 , wherein the two or more nickel salts comprise nickel acetate and nickel sulfate salts, and a proportion of the nickel acetate to a total of the nickel acetate and the nickel sulfate salts is 70 to 98 mol %.
