Abstract

This study investigates the influence of dopant content and firing conditions on electrical properties and positive temperature coefficient of resistance (PTCR) effect of Ba $_{1.005}$ $_{1.005}$ (Ti $_{1 - x}$ $_{1 - x}$ Nb $_{x})$ $_{x})$ O₃ (BTN) ceramics sintered at different temperatures from 1070 $^{\circ}$ $^{\circ}$ C to 1220 $^{\circ}$ $^{\circ}$ C for 2 h in a reducing atmosphere and reoxidized within the temperature range of 600–750 $^{\circ}$ $^{\circ}$ C for 0.5–8 h. The results indicate that the room-temperature (RT) resistance of the laminated BTN specimens initially decreased and then increased as a function of the dopant concentration. Moreover, the resistance jump exhibited a contrasting tendency. Furthermore, the RT resistance of the BTN samples rapidly decreased at first and then gradually decreased with increasing sintering temperature. Meanwhile, the resistance jump of the samples increased first and then decreased. In addition, the influence of reoxidation times on the PTCR characteristics of ceramics was investigated.
