| 2 | Relationship between tolerance factor and temperature coefficient of permittivity of temperature-stable high permittivity BaTiO_(3)–Bi(Me)O_(3) compounds显示文摘The temperature coefficient of permittivity(TCε)of BaTiO_(3)–Bi(Me)O_(3) solid solutions were investigated.It was determined that as the tolerance factor was decreased with the addition of Bi(Me)O_(3),the TCε shifted from large negative values to TCε values approaching zero.It is proposed that the different bonding nature of the dopant cation affects the magnitude and temperature stability of the permittivity.This study suggests that the relationship between tolerance factor and TCε can be used as a guide to design new dielectric compounds exhibiting temperature-stable high permittivity characteristics,which is similar to past research on perovskite and pyrochlore-based microwave dielectrics. | Natthaphon Raengthon Connor McCue David PCann | 2016 | Journal of Advanced Dielectrics2016，6，1： | 0 |
