Abstract

Low-temperature (50-60°C) anodic oxidation of porous titanium bodies in an aqueous electrolyte containing Ba²⁺ in solution has been used to infiltrate BaTiO₃ 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 BaTiO₃ surface using electroless plating techniques
