CORE-SHELL COMPOSITE AND ITS MANUFACTURING METHOD
To provide: a core-shell composite capable of maintaining a desired hydrogen-absorbing-and-releasing capability or the like to thermal hysteresis; and its manufacturing method.SOLUTION: A core-shell composite 1 includes: a core part 10 having rigidity and containing a refractory material made of inorganic oxide, ceramics, ore and the like; and at least one layer of shell parts 20 surrounding the core part 10 and containing a hydrogen-absorbing-and-releasing metal. The refractory material contained in the core part has a melting point higher than the most highest one among the hydrogen absorbing and releasing metal contained in the shell parts. The shell part 20 has a lamination part formed by laminating a plurality of multi-metal layers 21, 23, 25, and 27 containing a plurality of metals (Ni, Al) that constitutes the hydrogen-absorbing-and-releasing metal. A manufacturing method of the core-shell composite coats the shell part on the core part by depositing under non-presence of oxygen, when manufacturing such a core-shell composite.SELECTED DRAWING: Figure 1
【課題】熱履歴に対して所期の水素吸放出能等が劣化し難く、水素吸放出能が向上し得るコアシェル複合体及びその製造方法を提供する。【解決手段】コアシェル複合体１は、無機酸化物、セラミックス及び鉱物等の耐熱性材料を含み剛性を有するコア１０部と、コア部１０を包囲し水素吸放出性金属を含むシェル部２０を備える。コア部に含まれる耐熱性材料は融点がシェル部に含まれる水素吸放出性金属のうちの最も高いものの融点よりも高い。シェル部２０は、水素吸放出性金属を構成する複数種の金属（Ｎｉ，Ａｌ）を含むマルチ金属層２１，２３，２５及び２７が複数層積層した積層部を有する。コアシェル複合体の製造方法は、上述のようなコアシェル複合体を製造するに際し、酸素不存在下の蒸着によってシェル部をコア部に被覆する。【選択図】図１
