| Abstract: | In order to obtain the ceramic devices with good PTC effect,we find it very important to prepare the ceramic powder at first.Now with citrate sol-gel process and twice-through method,at low temperature sintered,the donor-doped BaTiO_(3) powder without lead has been prepared.Results show that the PTC powder is the powder with fine crystallization,well dispersion,low aggregation,nanometer scale.It have been studied by the methods of TG-DTA,XRD,SEM,TEM. |

| Keywords: | citrate sol-gel method twice-through synthetic double donor doping PTC material |
