Abstract

In this paper, the effects of Eu₂O₃ doping on the microstructure and electrical properties of ZnO-Bi₂O₃-Co₂O₃-TiO₂-MnO₂ (ZBCTM) varistors were investigated. After doping with Eu₂O₃, the formation of the secondary phase Bi₄Ti₃O₁₂ was promoted. The leakage current density and average grain size firstly decreased and then increased, and the height of the double Schottky barrier, the breakdown field strength, and the nonlinear coefficient firstly increased and then decreased. When the doping amount of Eu₂O₃ was 0.3 mol%, the resulting ZnO varistor exhibited a nonlinear coefficient of 60, the breakdown field strength was 744 V/mm, the leakage current density was 3.77 μA/cm²,and degradation rate of 6.2 × 10⁻³ mA h^1/2. The samples exhibit optimal electrical properties and electrical stability. It indicates that the prepared samples offer the advantages of low cost and low loss. It provides a reference for the preparation of Eu₂O₃-doped high-performance ZnO varistors.

Eu2O3掺杂高性能ZnO-Bi2O3基压敏电阻的制备及其电性能

本文研究了Eu2O3掺杂对ZnO-Bi2O3-Co2O3-TiO2-MnO2 （ZBCTM）压敏电阻微观结构和电性能的影响。Eu2O3掺杂后，促进了二次相Bi4Ti3O12的形成。泄漏电流密度和平均晶粒尺寸先减小后增大，双肖特基势垒高度、击穿场强和非线性系数先增大后减小。当Eu2O3掺杂量为0.3 mol%时，ZnO压敏电阻的非线性系数为60，击穿场强为744 V/mm，泄漏电流密度为3.77 μA/cm2，降解率为6.2 × 10−3 mA h /2。样品表现出最佳的电性能和电稳定性。结果表明，所制备的样品具有成本低、损耗小的优点。为制备掺杂eu2o3的高性能ZnO压敏电阻提供了参考。

期刊介绍： Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties. Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour. Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
