Flame retardant bond magnet.

摘要

The present invention provides a flame retardant bond magnet composed of a flame retarder and an organic binder in addition to alloy magnet powders with mean grain size 10 mu m or less represented by a general formula RM5 (where R denotes a rare earth metal element, and M a transition metal element), which is coated on their surfaces with an oxidation resistant inorganic substance. The flame retardant bond magnet of this invention is finding wide uses in electric equipment as sensor field magnets, various drive magnets, convergence correction magnets, etc.
