  • Process for preparing superconducting films by radio-frequency-generated aerosol plasma deposition
    Patent number: 5100868
    Abstract: A two-step process for the preparation of a thallium-containing superconductive film is described.In the first step of this process, an aerosol mist containing reactants necessary to produce a calcium/barium/strontium/copper precursor material is provided. This mist is subjected to radio-frequency radiation while in the plasma region, and it thereafter is deposited onto an electrically grounded substrate.In the second step of the process, the coated substrate is contacted with thallium-containing vapor.
