The influence of oxygen reducing tantalum powder surface fabric on the properties of tantalum pewder
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.
