【Abstract】 Polycrystalline iron fiber is a novel magnetic material, which can be used widely in industry. The relevant issues of thermodynamics were analyzed for pyrolysis of carbonyl iron in theory. On the basis of the theory of pyrolysis of carbonyl and the magnetic, the realizability for the method is proved. The method of pyrolysis of carbonyl with introducing magnetic field can produce polycrystalline iron fiber with controllable geometry size.更多还原
