CCTO掺杂对BaTiO3-Nb2O5-Co3O4陶瓷系统介电性能的影响
Effects of CCTO doping on the dielectric properties of BaTiO3-Nb2 O5-Co3O4 ceramic system
摘要
Abstract
In this paper, the ceramic of BaTiO3- Nb2O5-Co3O4 (BTNC) systems was studied as the main object, in order to research the effect of the system dielectric properties by adding CaCu3Ti4O12 (CCTO). It was found that, in the range from 20 ℃ to 85 ℃ , the dielectric constant of BT system, which was doped 3. 0% CCTO, reached 2 600 or more, and the temperature stability was △C/C≤4. 7%; in the range from 20 ℃ to 125 ℃ , the dielectric constant of BTNC system, which was doped 2. 0% CCTO, reached 2 700 or more, and the temperature stability was AC/C<10%; which was doped 4. 0% CCTO, reached 2 200 or more, and the temperature stability was △C/C≤5%.关键词
