Abstract
The use of high CV tantalum powders (3)2 impregnation of pellets produced with high CV powders obligates to found new developments in production process. For that purpose, the use of new materials and optimization of process parameters has been researched. The addition of surfactants to lower the free energy of the liquid/solid interface (interfacial tension) and new developments in the impregnation/pyrolysis process have been tested in order to get large and homogeneous surface coverage. Intermediate measurements allow a sequence control during impregnation development being used in our assessments. Traditional coverage measurements and high resolution Scanning Electron Microscope (HR-SEM) analysis are used to quantify the converted MnO2. Additionally, physical features of the MnO2 inner coat are compared. The electrical parameters as DF (Dissipation Factor), DCL (DC Leakage) and ESR (Equivalent Series Resistance) are measured to verify the experimental samples reliability.
