Latest Patents

Iijima's latest patents focus on the production processes of powdered tantalum and niobium. His innovations include a method for creating a porous sintered body and solid electrolytic capacitors using these powders. The process involves dissolving a tantalum or niobium ion source in molten salt, followed by the action of a reducing agent. This results in the reduction of tantalum or niobium ions to their metal state, yielding a powder that consists of aggregated columnar particles. The resulting tantalum or niobium powder features radially aggregated particles, which enhance the surface area and reduce the risk of failure in forming a solid electrolyte film.
