    Hi All,

    I hope you can help me with my quest,

    I need advice about corrosion-resistant materials to use as electrodes for a form of a capacitor
    that uses saline brine electrolyte - am not able to change the electrolyte so that is why I need to source
    the electrodes that will cope with the salinity.

    I am aware of things like carbon and stainless steel.

    Many thanks
    seza

    If you are making a capacitor, could you use a thin coating of insulation (lacquer etc) over copper etc plates?

    Thanks Alec,
    I think a layer of lacquer might be too fragile for my setup,
    some metal rods/tubes will do the trick ... but which metal(s) is the question?

    Alec,
    On a second though I am keen to find out more about the lacquer coating idea? any particular make? type etc ...

    thanks
