METHOD OF PRODUCING ELECTROLYTIC CAPACITOR WITH AL-TI ANODE BODY

摘要

A method of producing an Al-Ti alloy solid electrolytic capacitor comprising the steps of forming a porous Al-Ti alloy body, anodizing the Al-Ti alloy body thereby forming an oxide layer onto said Al-Ti alloy body, and heating the anodized Al-Ti alloy body in an oxygen atmosphere at a temperature of 500 DEG C to 700 DEG 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.
