    摘要： A method of producing an AI-Ti alloy solid electrolytic capacitor comprising the steps of forming a porous AI-Ti alloy body, anodizing the AI-Ti alloy body thereby forming an oxide layer onto said AI-Ti alloy body, and heating the anodized AI-Ti alloy body in an oxygen atmosphere at a temperature of 500°C to 700°C. Preferably that oxygen atmosphere can be air. The temperature of the heating in oxygen atmosphere is selected such that the dielectric loss of the heated oxide layer becomes lower than the initial dielectric loss of said oxide layer prior to said heat treatment.

    摘要： A porous sintered body for an Al-Ti alloy solid electrolytic capacitor comprises a porous body of Al-Ti alloy and a titanium lead wire partly embedded in the porous body. The titanium lead wire is subjected during manufacture to a nitriding treatment and is sintered together with the Al-Ti body so that the surface of the lead wire is converted into an Al-Ti alloy. In one method of producing the porous sintered body, a titanium wire is heat-treated in a nitrogen atmosphere, the wire is then embedded in a mixture of aluminium powder and titanium powder or titanium hydride powder, the mixture is press-moulded with the wire and the press-moulded article is sintered. A solid electrolytic capacitor and a method for manufacturing such a capacitor employing the porous sintered body are disclosed. The invention provides a porous sintered body with an embedded lead wire in which the lead wire is inexpensive and has good electrical characteristics and which avoids the problem of bending deformation of the wire after sintering.

    摘要： A process for producing a porous body for use as an electrode for a solid electrolytic capacitor. In the process, titanium powder having an average particle size from 10 to 30 µm is mixed with aluminium powder having an average particle size from 1/6 to 1/2 of that of the titanium. The mixture is then compression molded and heat treated in a vacuum or inert gas to diffuse the aluminium into the titanium. In the product the surface of the titanium-aluminium particles has a fine ruggedness of size from 0.5 to 5 µm. The aluminium content of the titanium-aluminium alloy is from 50 to 70 atomic %.
