Production of semiconductor ceramics having positive temperature coefficient of resistance |
| abstract |
PURPOSE: To prevent the occurrence of unevenness in dielectric strength as well as to enhance the dielectric strength while keeping specific resistance low. n CONSTITUTION: CaCO 3 having ≥2m 2 /g specific surface area and ≤3.0μm average particle diameter as starting material for Ca is added to barium titanate-based material as a principal component and they are calcined. n COPYRIGHT: (C)1992,JPO&Japio |
