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.
