摘要
对钽粉降氧出炉后的表面物料及内部物料酸洗后的各项性能进行了比较分析,重点分析了钽粉表面与内部物料酸洗后物料性能、化学性能、电性能的变化.研究表明降氧过程表面物料的松装密度、费氏粒径较内部物料的费氏粒径、松装密度偏大,表面物料的杂质含量及漏电流明显高于内部物料.
Abstract
The properties of surface and internal materials after acid pickling of tantalum powder were com-pared and analyzed,especially the changes of properties,chemical properties and electrical properties between tantalum powder surface and normal materials after acid pickling.The results show that the bulk density and Fischer particle size of the surface materials are larger than those of the normal materials,the metal impurity,content and leakage current of the surface material are obviously higher than those of the internal material.
