Compressed non-bonded magnet - possible?

    Compressed "non-bonded" magnet - possible?

    Dear everyone
    As opposed to a bonded magnet being magnet powder "glued" together with e.g. epoxy and which is incapsulated as to prevent corrosion - does anyone know if one can instead compress magnet powder without a binder directly in a can-like object and seal it of hermetically afterwards? And if so, who is capable of manufacturing such an incapsulated and "non-bonded" magnet?
    Thank you millions in advance for your time and consideration.

    Ceramic magnets are fairly non-reactive, but I've seen them over-molded with Teflon for an ultrapure application. Of course, you have to pay for an injection mold.

    Good luck,

    Aside from bonded magnets, there are also sintered magnets, would those suit your purposes?
