High-entropy oxides with complex compositions can be designed as novel ferroelectric materials with interesting physical consequences. A single-phase (K0.5Bi0.5)0.2Ba0.2Sr0.2Ca0.2Mg0.2TiO3 high-entropy ceramic with a perovskite structure was synthesized by a conventional high-temperature solid-state method, and the dielectric and ferroelectric properties of the ceramic were investigated. The results show that there are no relaxation peaks in the test temperature range because of the multi-element doping. The dielectric constant of ceramic has a high-temperature stability at < 300 ℃. The maximum dielectric constant of 8 887 is obtained at 100 Hz and 650 ℃. The introduction of high-entropy oxide in the ceramic can have high-entropy ferroelectrics in complex materials, and modify the properties of electronic ceramic.

复杂成分的高熵氧化物可以设计成具有有趣物理现象的新型铁电材料。通过传统高温固相法成功地合成了一种单相钙钛矿结构(K0.5Bi0.5)0.2Ba0.2Sr0.2Ca0.2Mg0.2TiO3高熵陶瓷,研究了其介电性能和铁电性能。多元素掺杂使得陶瓷在测试温度范围内没有观察到明显介电弛豫峰。低于300 ℃时,陶瓷介电常数温度稳定性较高。当测试温度为650 ℃,频率为100 Hz时,得到最大的介电常数8887。结果表明:高熵概念的引入不仅在成分复杂的材料中可以发现新的高熵铁电体,而且是调节电子陶瓷性能的可行策略。

复杂成分的高熵氧化物可以设计成具有有趣物理现象的新型铁电材料。通过传统高温固相法成功地合成了一种单相钙钛矿结构(K0.5Bi0.5)0.2Ba0.2Sr0.2Ca0.2Mg0.2TiO3高熵陶瓷,研究了其介电性能和铁电性能。多元素掺杂使得陶瓷在测试温度范围内没有观察到明显介电弛豫峰。低于300 ℃时,陶瓷介电常数温度稳定性较高。当测试温度为650 ℃,频率为100 Hz时,得到最大的介电常数8887。结果表明:高熵概念的引入不仅在成分复杂的材料中可以发现新的高熵铁电体,而且是调节电子陶瓷性能的可行策略。

High-entropy oxides with complex compositions can be designed as novel ferroelectric materials with interesting physical consequences. A single-phase (K0.5Bi0.5)0.2Ba0.2Sr0.2Ca0.2Mg0.2TiO3 high-entropy ceramic with a perovskite structure was synthesized by a conventional high-temperature solid-state method, and the dielectric and ferroelectric properties of the ceramic were investigated. The results show that there are no relaxation peaks in the test temperature range because of the multi-element doping. The dielectric constant of ceramic has a high-temperature stability at < 300 ℃. The maximum dielectric constant of 8 887 is obtained at 100 Hz and 650 ℃. The introduction of high-entropy oxide in the ceramic can have high-entropy ferroelectrics in complex materials, and modify the properties of electronic ceramic.
