对影响钽片电容性能的主要因素进行了分析,并进行了各种条件试验和检测。指出钽粉的原始粒度、碳、氧含量的配比以及烧结温度、烧结时间等均对钽片的漏电系数有明显的影响。要根据原始钽粉中碳、氧及其他杂质的含量进行必须的氧含量计算,再配入适当的氧化钽,其次进行粉末粒度的配比,最后选择最佳烧结工艺,配用适当的润滑油进行轧制,可获得极为满意的优质钽片。
The main factors affecting the performance of tantalum chip capacitors were analyzed, and various conditions were tested and tested. It is pointed out that the primary particle size, the ratio of carbon and oxygen, the sintering temperature and the sintering time of tantalum powder all have obvious influence on the leakage coefficient of tantalum. According to the original tantalum powder carbon, oxygen and other impurities in the content of the necessary oxygen content calculation, and then with the appropriate tantalum oxide, followed by the powder size ratio, the final choice of the best sintering process, with the appropriate lubricant For rolling, very satisfied with the quality of tantalum tablets.
