発明の名称 (英語) Fine solid solution alloy particles and method for producing same NEW
発明の概要(英語) (US9540712)
The alloy fine particles of the present invention are fine particles of a solid solution alloy, in which a plurality of metal elements are mixed at the atomic level.
The production method of the present invention is a method for producing alloy fine particles composed of a plurality of metal elements.
This production method includes the steps of (i) preparing a solution containing ions of the plurality of metal elements and a liquid containing a reducing agent; and (ii) mixing the solution with the liquid that has been heated.
特許請求の範囲(英語) [claim1]
1. Fine particles of a solid solution alloy, in which a plurality of metal elements are mixed at the atomic level wherein the plurality of metal elements are a plurality of metal elements that do not form a solid solution even in the liquid phase.
[claim2]
2. The alloy fine particles according to claim 1, wherein the plurality of metal elements are two kinds of metal elements.
[claim3]
3. The alloy fine particles according to claim 2, wherein elemental mapping using a scanning transmission electron microscope with a resolution of 0.105 nm demonstrates that there is no phase separation in the alloy fine particles.
[claim4]
4. The alloy fine particles according to claim 2, wherein X-ray diffraction demonstrates that there is no phase separation in the alloy fine particles.
[claim5]
