    摘要： Capacitor anodes that include metallic columns formed on a substrate so as to form a porous microstructure and methods of making the anodes are described. The metallic columns can be distinct from one another and project outward from the substrate. Also described is the formation of the metallic columns on the substrate by vapor deposition, including glancing angle deposition (GLAD), and by etching a portion of a metal layer. High capacitance capacitors made from the capacitor anodes are also described.

    摘要： Methods of forming tantalum powders and other valve metal powders are described. The method involves high impact milling a starting powder in a fluid medium and optionally a milling media using a high energy mill. The methods of the present invention have the ability to reduce DC leakage and/or increase capacitance capabilities of valve metal powders when formed into capacitor anodes. The methods of present invention further reduce the milling time necessary to form high surface area valve metal powders and leads to reducing contaminant levels in the valve metal powders. The process is particularly well-suited for forming metal flakes, such as tantalum or niobium flakes, of high purity.
