I frequently read about different mixture of ferrite used to make cores used
for different frequency. Over the years I managed to accumulate a box of
different cores. There are lots of different colors, from light yellow you
purple, sizes ranging from 3\8 to 4 inch, and shapes from simple round to
square and lots in between
Those are not ferrite cores, they are powdered iron, and are widely used
as cores for inductors.
