| Abstract: | The burning system has a great influence on the dielectric properties of BaTiO3 based PTC ceramics.The influence of burning temperature,the heat preservation time,cooling process and the atmosphere on the resistance in room temperature and PTC effect of BaTiO3 based ceramics was discussed in detail in this paper and a reasonable explanation of mechanism was also given.The results in the experiments indicated that there is close relationship between burning temperature and transformation of ceramics to semiconductor.Appropriate preservation time greatly effects the transfer of substance.At the same time,cooling process and the atmosphere has influence on the resistance in room temperature and PTC effect. |
| Keywords: | PTC effect burning system BaTiO3 ceramic |
