Influence of Reaction Time on Properties of BaTiO₃ Coated Ni Nanoparticles by a Novel Sol-Precipitation Method

Abstract:

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.
