【Abstract】 The resistance of a PTCR is consisted of grain resistance, grain boundary re-sistance and contact resistance. In this paper, the influence of the composition and theprocessing conditions of a PTCR on its resistance is discussed in detail. The resistanceafter sintering can be adjusted by retreatment to access the wanted value.更多还原
