ABSTRACT:
Iron is used as a dopant in barium titanate semiconductor ceramic material to increase the positive temperature coefficient of resistance thereof. By the use of about 0.010 to 0.500 weight percent silica and about 0.0075 to 0.0190 weight percent iron, room temperature resisitivity can be kept adequately low while the temperature coefficient of resistance is significantly increased.
