Abstract Manganese-doped lead zirconate ceramics were prepared by a conventional solid reaction method. Although the doping content varies from 5% (mole) to 20% (mole), significantly enhanced universal dielectric relaxation occurs only in 5% Mn-doped lead zirconate. The behavior cannot be properly explained by Maxwell-Wagner relaxation, which is commonly used for explaining giant dielectric permittivity in electroceramics. It is found that the enhanced giant dielectric permittivity is related to hetero-valence cation doping induced universal dielectric relaxation.

Mn掺杂PbZrO3陶瓷中的普遍介电弛豫诱导巨介电常数

摘要 采用常规固相反应法制备了锰掺杂锆酸铅陶瓷。尽管掺杂含量从 5%（摩尔）到 20%（摩尔）不等，但仅在 5% Mn 掺杂的锆酸铅中出现显着增强的普遍介电弛豫。麦克斯韦-瓦格纳弛豫无法正确解释这种行为，麦克斯韦-瓦格纳弛豫通常用于解释电陶瓷中的巨介电常数。发现增强的巨介电常数与异价阳离子掺杂引起的普遍介电弛豫有关。
