    • Abstract
  • The FTA500 grade tantalum powder with the capacity of 50 000 μF·V/g is chosen to explore the effect of the molding and sintering processes on electrical properties of tantalum anode. The results show that the opening ratio and capacity of tantalum anode block decrease with the increase of pressing density. When the pressing density is 5.00 g/cm3, the leakage current coefficient of anode block is the lowest. With the increase of sintering temperature, the sintering density increases, the specific capacitance and the leakage current coefficient decrease, the loss of tantalum anode increases, the volume shrinkage increases, and the breakdown voltage increases.
