| Abstract: | Barium titanate（BaTiO3）is widely used in preparation of capacitance,thermal resistor,energy conversion device,for their exceptional ferroelectric,piezoelectric,pyroelectric and dielectric properties.Especially,it is mostly applied in making multilayer ceramic capacitor（MLCC） materials.At present,MLCC has a trend of high credibility,specific votume（small size and large capacity）and low cost.So,researchers have paid their attention to the preparation of high pure BaTiO3 nanopowders,and doped BaTiO3.In this paper,the monodisperse Nd（OH）3,Co3O4,Nb2O5 and nano complexly doped BaTiO3 ceramics was prepared and the effect of particle size of nano-dopant on the microstructure and dielectric properties of nano-doped BaTiO3 was investigated. |
