摘要
讨论了掺杂Y2O3的BaTiO3陶瓷的介电特性,并计算了晶粒电阻、晶界电阻、晶界宽度和晶界势垒高度。
The dielectric characteristics of BaTiO 3 ceramics doped with Y 2O 3 has been discussed. Grain resistance, the width of grain boundary and the potential barrier are calculated. The influences on both micro-structure and macro-properties of (YBa)TiO 3 material with the addition of a little amount of Li 2CO 3 are also studied.
