ABSTRACT |
Bodies whose compositions are in the ternary system BaCO3-TiO2-SnO2 containing from 5 to 90 mol % stannic oxide were prepared to improve the thermal characteristics of barium titanate dielectrics. Bodies having dielectric constant (K) of 2100 at 1 KHz, low negative temperature coefficients of 1500ppm up to about 9$0^{circ}C$, Curie Temperature of 2$0^{circ}C$, and dissipation factor of 0.2-0.4% were obtained with addition of 15 mole % stannic oxide. |
