Abstract
Official abstract text for this publication.
This disclosure provides a hydrogen storing alloy and a production method thereof. The hydrogen storing alloy has a chemical composition of a general formula R(1-x)MgxNiy, wherein R is one or more elements selected from rare earth elements comprising Y, x satisfies 0.05≤x≤0.3, and y satisfies 2.8≤y≤3.8. The ratio of the maximal peak intensity present in a range of 2θ=31°-33° to the maximal peak intensity present in a range of 2θ=41°-44° is 0.1 or less (including 0), as measured by X-ray diffraction in which a Cu—Kα ray is set as an X-ray source.
First claim
Opening claim text (preview).
What is claimed is: 1. A hydrogen storing alloy, wherein the ratio of the maximal peak intensity present in a range of 2θ=31°-33° to the maximal peak intensity present in a range of 2θ=41°-44° is 0.1 or less and includes 0, as measured by X-ray diffraction in which a Cu—Kα ray is set as an X-ray source, wherein the hydrogen storing alloy has a chemical composition of La (1-a-b) Y a Mg b Ni c Al d , wherein a satisfies 0.12≤a≤0.15, b satisfies 0.14≤b≤0.16, c satisfies 3.39≤c≤3.53, and d satisfies 0.13≤d≤0.17.
