| Summary: | Uniform BaTiO3 polycrystalline coating layer on Ni nanoparticles is achieved by a novel sol-precipitation method. The Fourier transform infrared spectra (FT-IR) of the coated samples inhibit that there is typical Ba-O and Ti-O bond for crystalline BaTiO3.The influence of reaction time on the properties of the coated samples is investigated. It is found that the coating layer contains less BaCO3 impurity and crystallizes more completely along with the increase of the reaction time. Moreover, the anti-oxidation properties of these samples are significantly improved. |
