    • An ultrafine Al particle consists of an Al multiply twinned particle. The Al multiply twinned particle has a decahedron structure surrounded by {111} planes. The Al multiply twinned decahedral particle has a diameter of 10 to 30 nm. Such an ultrafine Al particle consisting of the Al multiply twinned decahedral particle is obtained as follows. A metastable Al oxide particle is placed on an amorphous carbon substrate having the reduction effect. Then the electron beam is irradiated to the metastable Al oxide particle placed on the amorphous carbon substrate in the vacuum atmosphere. From the metastable Al oxide particle, Al atoms or Al clusters are emitted and adsorbed to the substrate. By adjusting the electron beam intensity so that the ultrafine Al particle in the above procedure has a diameter from 10 to 30 nm, the Al multiply twinned particle having a decahedron is obtained.
    • 超细Al颗粒由Al多重孪晶颗粒组成。 Al多重孪晶颗粒具有被{111}平面包围的十面体结构。 Al多重双晶十面体粒子的直径为10〜30nm。 由Al多重双晶十面体粒子组成的这种超细Al粒子如下获得。 将亚稳态Al氧化物颗粒放置在具有还原效果的非晶碳衬底上。 然后在真空气氛中将电子束照射到放置在非晶碳基板上的亚稳态Al氧化物颗粒。 从亚稳态Al氧化物颗粒中,Al原子或Al簇被发射并吸附到衬底上。 通过调整电子束强度,使上述方法中的超细Al粒子的直径为10〜30nm,得到具有十面体的Al倍增孪晶粒子。

    • An onion-like graphite 2 is produced by irradiating an electron beam to an amorphous carbon 3 under an active aluminum nanoparticle 1. By further irradiating the electron beam to the onion-like graphite 2 to intercalate aluminum atoms constituting the aluminum nanoparticle 1 in a space between (001) plane and (002) plane of the onion-like graphite 2 having a layer structure, an intercalation compound 4 is produced. Or, after the aluminum nanoparticles were driven and disposed on the onion-like graphite by electron beam, or the like, by irradiating the electron beam to intercalate aluminum atoms in the space between the (001) plane and the (002) plane of the onion-like graphite having a layer structure, the intercalation compound is produced.
