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
