PTC thermistor ceramic composition and PTC thermistor element |
| abstract |
The present invention aims to provide a barium titanate-based PTC thermistor ceramic composition without using Pb. Your Curie temperature is shifted to a higher temperature than 120 ° C. The PTC thermistor can immediately become semiconductive, even when sintered in air. The resistivity at 25 ° C is low and the rate of change of resistivity at 25 ° C is low with time. The PTC thermistor ceramic composition comprises a sintered body having a barium titanate-based compound represented by the formula (1) as the main component. (Ba 1-xyw Bi x A y RE w ) α (Ti 1-z TM z ) O 3 (1), where 1.02y ≤ x ≤ 1.5y (2), 0.007 ≤ y ≤ 0.125 (3) 0 ≦ (w + z) ≦ 0.01 (4), 0.97 ≦ α ≦ 1.06 (5), and the sintered body Ca in a ratio of 0.01 mol or more and less than 0.05 Mol contains relative to 1 mole of a Ti site as an element. |
