Abstract
Al-In composite nanoparticles were prepared by the condensation of In vapor onto flying Al nanoparticles which were produced in advance by a gas-evaporation technique. The structural and morphological observation of these nanoparticles was carried out by means of a transmission electron microscope. It was found that the particle is composed, of an Al sphere with an In crystallite sticking to the Al surface. It is concluded that the particles grow through three steps; first, Al nanoparticles grow, then, they melt and re-evaporate due to subsequent heating, and last, In vapor condenses onto them.
