发布时间：2018-10-12 19:18
【摘要】：采用DOE实验设计方法,对制备电容器用铌粉的酸洗除杂工艺进行研究,确定了影响铌粉性能的关键因素是酸洗除杂工艺使用酸的浓度和酸洗时间。通过关键因素的全因子正交试验,对产品质量和工艺参数进行量化分析,确定最佳的酸洗工艺,可有效减低和控制电容器级铌粉中的主要C、O非金属及Fe、Ni、Cr金属杂质含量,降低电容器级铌粉的漏电流和损耗,提高电容器级铌粉的性能。
[Abstract]:The acid pickling process for the preparation of niobium powder for capacitors was studied by means of DOE experimental design. The key factors affecting the performance of niobium powder were the concentration of acid and the pickling time. By means of the all-factor orthogonal test of the key factors, the product quality and technological parameters were analyzed quantitatively, and the optimum pickling process was determined, which can effectively reduce and control the main metal impurities in the condenser grade niobium powder, such as Con O nonmetal and Fe,Ni,Cr metal impurity. The leakage current and loss of capacitor grade niobium powder are reduced, and the performance of capacitor grade niobium powder is improved.
