The effect of different sinter atmosphere on the properties of the positive temperature coefficient resistivity(RTCR) is researched. The room temperature resistivity(ρ 0) of RTCR sintered under CO 2 atmosphere is reduced nearly 50 percent, but other preperties don′t vary remarkly. So sintering under CO 2 atmosphere is an effective process method for achieving low resistivity.
