【Abstract】 Zr is deposited on the substrates with ion beam sputtering, at the same time, with oxygen ion beam bombarding. It is found that zirconium oxides formed from amorphous to crystallites are dependent on the densities of the bombarding oxygen ion beam, where the size of the crystallite is in the range of nm particles. And the critical densities of the bombarding oxygen ion beam for the formation of the nm particles are different from different substrate materials. Also the phase structure and chemical composition of the nm particles are analyzed in this paper.更多还原
