  • Barium titanate film synthesizing process
    Patent number: 7077943
    Abstract: A new technique to synthesize barium titanate (BaTiO3) on homogeneous substrates (titanium) or heterogeneous substrates (silicon wafers, metal, glass, ceramics, polymers, other metals, etc.) is disclosed to include a first step to deposit a titanium film on a substrate by sputtering, and a second step to synthesize barium titanate film with uniformly dispersed spherical particles on the titanium-coated substrate in a electrolyte containing barium ions by electrochemically anodic oxidation.
    Type: Grant
    Filed: July 3, 2003
    Date of Patent: July 18, 2006
    Assignee: National ChungHsing University
    Inventors: Fu-Hsing Lu, Chu-Tsun Wu
