摘要：
A method of continuously generating a joined structure: comprising a cube- or quadratic prism-shaped rock salt-type oxide nanoparticle and a metal nanoparticle, and having high crystallinity, in a gas phase, the method is characterized in that alloy nanoparticles composed of a noble metal and a base metal and having a particle size of 1 to 100 nm are generated in an inert gas; and brought into contact with a hot oxidizing gas, while the nanoparticles are heated at a high temperature together with the inert gas, to oxidize a base metal component in the alloy nanoparticles floating in the gas, and to simultaneously allow phase separation of the metal component, whereby the joined structure.
