| 摘 要： | 钽铌属于同族元素 都是阀金属材料，其介电常数分别为27、41，都可以用来制作电解电容器。本文使用铌和钽2种材料分别制作电解电容器，并通过容量损耗测试仪、漏电流测试仪、电子扫描电镜等分析仪器对其和始性能、偏压性能、温度特性、寿命特性及其电介质层的微观特性进行检测分析。结果表明使用铌材料同样可以得到性能较好的电解电容器。

| Abstract: | Ta and Nb are elements in the same group and both one of valve metal materials, whose dielectric constant are 27 and 41 respectively. Both of them can be used in the manufacture of electrolytic capacitors. In the study work, we fabricated Ta and Nb electrolytic capacitors by using Ta and Nb materials respectively. Through using many kinds of instrument such as LCR meter, DLC (DC Current Leakage) tester and SEM, we made tests and analyses on the initial properties, DC bias, temperature dependent and life performance as well as the microstructure and characteristics of the dielectric film. The result shows Nb as a material could be used to produce Nb electrolytic capacitor with better performance. |
