Abstract: A reaction vessel for making phlegmatized metal powder or alloy powder has a retort crucible with a heat-proof, coolable cover, a heatable reduction furnace into which the retort crucible may be inserted, and an inner crucible placed within the retort crucible and removable therefrom. At least one inlet is built into the coolable cover for adding a passivating gas. A heat-proof flange welded onto the retort crucible attaches the retort crucible to the heat-proof, coolable cover. A cooler welded onto a lower face of the heat-proof flange provides a cooling agent to the reaction vessel.

Abstract: An object of the present invention is to provide nitrogen-containing metallic powder at high productivity, which powder contains a metal such as niobium or tantalum containing nitrogen uniformly, and enables production of an anode electrode that has high specific capacitance and low leakage current and that exhibits excellent reliability for a prolonged period of time. There is provided nitrogen-containing metallic powder which is a solid solution containing 50-20,000 ppm nitrogen, in which the metal that constitutes the metallic powder is niobium or tantalum. The nitrogen-containing metallic powder is produced through the process in which while a metallic compound is reduced with a reducing agent, a nitrogen-containing gas is introduced into a reaction system to thereby form metal, and nitrogen is simultaneously incorporated into metal. A porous sintered body comprising the nitrogen-containing metallic powder and a solid electrolytic capacitor comprising the powder have low leakage current and exhibit excellent reliability for a prolonged period of time.
