摘要

本文综述了具有高（超过 10,000 ）相对介电率值的介电材料。这些材料的组成大多基于包含铁电和非铁电成分的系统，以及基于这些成分的固溶体。研究考虑了提高材料介电常数的各种方法，包括掺杂、烧结气氛、研磨时间、烧结温度和晶粒尺寸。比较了掺杂剂和合成方法对可用于低频和高频范围的电容器陶瓷特性的影响。

Ceramics with Ultrahigh Permittivity Values: Compositions, Synthesis Methods, and Properties at Low and Medium Frequencies

A review of dielectric materials with high (exceeding 10,000) values of relative permittivity is presented. Most of the compositions of these materials are based on systems that include ferroelectric and non-ferroelectric components, as well as solid solutions based thereon. Various approaches to increasing the permittivity of materials are considered, including doping, sintering atmosphere, grinding time, sintering temperature, and grain size. The effect of dopants and the synthesis method on the characteristics of capacitor ceramics that can be used in the low-frequency and high-frequency range are compared.
