| Abstract: | BaTiO 3 ceramics are widely applied in the field of electronic devices materials with small volume and large capacity due to its ferro-electric,piezo-electric and insulating properties,but its dielectric constant is often unstable at a range of working temperature.In the paper,BaTiO 3 modification methods were reviewed based on the recent research attractions.Meanwhile,the effect of incorporation of rare-earth on dielectric property of BaTiO 3 ceramics was introduced.Finally,the methods to improve the properties were put forward. |
