Preparation and characterization of barium titanate electrolytic capacitors by anodic oxidation of porous titanium bodies

Low-temperature (50-60 degrees C) anodic oxidation of porous titanium bodies in an aqueous electrolyte containing Ba/sup 2+/ in solution has been used to infiltrate BaTiO/sub 3/ onto a large surface area. Microstructural and dielectric characterization indicates the possibility of achieving extremely high capacitance values by further improving the porosity of the Ti bodies and electroding the BaTiO/sub 3/ surface using electroless plating techniques.<
