Abstract

Crystallized solid-solution oxide films, Ca1-XSrXTiO3, have been prepared on a titanium metal substrate in an electrolytic solution containing Sr2+ and Ca2+ ions by a modified hydrothermal-electrochemical method at a low temperature (150°C). The grain size became smaller from approximately 1.3 μm for CaTiO3 film to 0.3 μm for SrTiO3 film with an increase of Sr concentration. The composition of the solid-solution oxide films was investigated using Vergard's law and X-ray photoelectron spectroscopy. The Sr-to-Ca ratios in these films were even larger than those in the starting solutions.
