    Find material for ferrite core

    Hi!

    I want to make some ferrite core for microwave experiment, where can I find epoxy or silicone rubber for ferrite core?

    Re: Find material for ferrite core

    From a web article I got the idea to cut up steel wool into tiny slivers, and mix it into a slurry with silicone caulk/ sealant/ adhesive. Available in hardware and automotive stores.

    I tried it with short lengths of soda straw. The slurry was about a 50-50 mix. I made a messy job of tamping it into the straw. I wound about a hundred turns of thin wire. The result is 100 or 200 uH.

    Ferrites are ferromagnetic oxydes, ferrite cores are sintered like ceramics. In so far I don't see where epoxy or silicone resin comes into play.

    You can buy ferrite in just about an shape, size or configuration imaginable.
    I cannot imagine why you would want to make your own.
    Cheers, Tony.
