Patents by Inventor Kurt A. Habecker

Kurt A. Habecker has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7749297
    Abstract: A niobium powder is described which when formed into an electrolytic capacitor anode, the anode has the capacitance of at least 62,000 CV/g. Methods of making flaked niobium powder which have high capacitance capability when formed into electrolytic capacitor anodes is also described. Besides niobium, the present invention is also applicable to other metals, including valve metals.
    Type: Grant

  • Patent number: 7156893
    Abstract: Methods of forming niobium powders and other metal powders are described. The method involves milling the metal powders at elevated temperatures and in the presence of at least one liquid solvent. The methods of the present invention have the ability to reduce DC leakage and/or increase capacitance capabilities of metal powders when formed into capacitor anodes. The present invention further has the ability to significantly reduce the milling time necessary to form high surface area metal powders and leads to reducing the amount of contaminants in the metal powders. Metal powders such as niobium powders having reduced amount of contaminants and/or having DC leakage or capacitance capabilities are also described. A process is further described for forming a flaked metal by wet-milling a metal powder into a flaked metal wherein at least one liquid fluorinated fluid is present during the wet-milling process.
