| Abstract: | A series of Bao0.9Sr0.1Ti1-xNdxO3(0≤x≤0. 1) solid solutions were synthesized below 100℃ . XRD demonstrated that the compounds have a cubic system. Furthermore, through TEM, the product is found to have a shape of uniform, substantially spherical particles with an average particle size of 70 nm in diameter. The result of preparing ceramics showed that after adulterating with Nd in pure BaTiO3 phase, the dielectric constant increased thirty times at room temperature and the sintering temperature of the nano-powder was 1 150℃. |
