Abstract: A method for producing an electrical component via a 3D printing includes preparing a first layer which includes a valve metal powder, consolidating at least a portion of the valve metal powder of the first layer via a first selective irradiation with a laser, applying a second layer which includes the valve metal powder to the first layer, consolidating at least a portion of the valve metal powder of the second layer via a second selective irradiation with the laser so as to form a composite of the first layer and of the second layer, applying respective additional layers which include the valve metal powder to the composite, and consolidating at least a portion of the valve metal powder of the respective additional layers via a respective additional selective irradiation with the laser to thereby obtain the electrical component.

Abstract: A sintered body obtainable by a process which includes pressing a powder comprising or consisting of at least one valve metal so as to provide a pellet, providing the pellet together with a reducing agent so that the pellet is not in a direct contact with and does not come into a direct contact with the reducing agent, heating so that the powder in the pellet is sintered to form a sintered body, an oxygen content of the at least one valve metal within the sintered body is simultaneously reduced, and the reducing agent is oxidized to an oxidized reducing agent, and removing the oxidized reducing agent with at least one mineral acid.

Abstract: The present invention relates to a process for the deoxidation of valve metal primary powders by means of reducing metals and/or metal hydrides, and a process for the production of tantalum powders that are suitable as anode material for electrolytic capacitors.
