Carbonyl iron is a metallic iron which possess metallic magnetic properties.
Carbonyl iron has been used:
in the manufacture of bioactive membranes
in the manufacture of active magnetic fabrics (AMF)
for the fabrication of magnetodielectric tissues (MT)
Carbonyl iron has a role as an absorber of microwave radiation. Carbonyl iron also exhibits shielding properties because of the low density and the connectivity among the fillers it provide. It is used in industries and in the synthesis of nitro-group-containing pharmaceutical ingredients.
