Coating method for Titanium dioxide?

    As part of an experiment, I need to coat one side of a 150mm metal
    disk with TiO2. The metal can be anything that will produce the best
    result. Presently I have aluminium.

    What is the best option in terms of additives and technique for the
    following two outcomes.

    1. I simple immobilized layer painted (rolled) on with a
    self-hardening binder that will more or less homogenize the dielectric
    within the entire coating. What generic binder would best suit?

    2. A chemical or surface applied means that retains some
    semiconductive properties without resort to sol gel, sintering, etc.
    How effective is conductive paint as a binder for such a process.
    Would abrading the metal surface prior to improve efficiency?

    Thank you for your suggestions.

    Too much work and too expensive.
    Anodize it; the oxide *is* the surface and the controls are easy
    (surface contamination, surface porosity, surface smoothness, voltage,
    current, time, and PH to mention some of the important and controllable
    parameters).
