Abstract A lead-free electronic component Bi(Co2/3 V1/3)O3 has been fabricated using conventional solid-state technique. The conducting, capacitive and resistive properties of the synthesized element have extensively been investigated. An analysis of X-ray diffraction (XRD) data shows the formation of the electronic component in orthorhombic crystal symmetry. The uniform distribution of grains on the specimen surface has been identified through scanning electron microiscope (SEM). Detailed analysis of dielectric parameters ( e r , t a n δ ) substantiate the component as a dielectric. Study of impedance data reveals the contributions of bulk as well as grain boundary on the capacitive and resistive properties of the fabricated sample. The frequency and temperature-dependent ac conductivity spectrum obey Jonscher's power law. The existence of a negative temperature coefficient of resistance (NTCR) behaviour can be implied from the reduced grain resistance with temperature. The hysteresis loop (P-E) confirms the presence of ferroelectric property in the compound. The fabricated compound shows higher dielectric constant, low loss at high temperature (>200 °C), eco-friendly and can sustain in harsh environment ((>300 °C) thus it can be a stronger contender for functional devices.

环保电容元件的制造和电气特性：Bi(Co2/3V1/3)O3

摘要 使用常规固态技术制造了无铅电子元件 Bi(Co2/3 V1/3)O3。已广泛研究了合成元件的导电、电容和电阻特性。X 射线衍射 (XRD) 数据的分析表明电子元件以正交晶体对称的形式形成。样品表面晶粒的均匀分布已通过扫描电子显微镜 (SEM) 进行识别。介电参数 (er , tan δ ) 的详细分析证实该组件是电介质。阻抗数据的研究揭示了体积和晶界对制造样品的电容和电阻特性的贡献。频率和温度相关的交流电导率谱遵循 Jonscher 幂律。负温度系数电阻 (NTCR) 行为的存在可以从随温度降低的晶粒电阻来暗示。磁滞回线 (PE) 证实了化合物中存在铁电特性。所制备的化合物具有更高的介电常数、高温（>200°C）下的低损耗、环保且可在恶劣环境（（>300°C）中持续使用，因此它可以成为功能器件的有力竞争者。
