| Abstract: | The influence of the additives such as Nb2O5, La2O3, ZnO, NiO on sintering and dielectric properties of CaTiO3 ceramics was investigated. And the mechanism was also discussed. The results show that the proper additives can be decreased the sintering temperature and CaTiO3 can be sintered between 1 260℃ and 1 280℃. The temperature coefficient of CaTiO3 is found to be –1 000×10–6℃–1. At 10 kHz to 20 MHz,the material dielectric constant is 175 and dielectric loss is 10–4.The ceramic can be used as thermal compensation capacitor material. |
