Crystalline-oriented TiO2 fabricated by the electrophoretic deposition in a strong magnetic field

Electrophoretic deposition of titania (anatase) suspension was conducted in a strong magnetic field of 10 T. The direction of the electric field E relative to the magnetic field B was altered (ϕB–E=0, 30, 60 and 90°) to control the dominant crystal faces of the deposit surfaces. The crystalline orientation was investigated by the X-ray diffraction for the titania films of as-deposited, sintered at 650, 750 and 1200 °C as a function of the angle between the directions of B and E (ϕB–E). It was found that changing the angle ϕB–E during the EPD could control the crystalline orientation of the titania films.
