Porous and net-shaped tantalum powder for a capacitor was formulated in a SHS (self-propagating
high-temperature synthesis) process. However, this powder, which has weak strength among its particles and
low flow ability, cannot be used for a capacitor. Therefore, this powder was sintered in a high-vacuum furnace
to increase agglomeration to improve the flow ability, bonding strength among the particles, and shrinkage
during pellet sintering. Finally, it was deoxidated with 2 wt% Mg powder to remove the increased surface
oxygen that arose during the sintering process. The final product was analyzed in terms of its chemical and
physical properties and was compared with a commercial powder used by a capacitor manufacturer.
