| Abstract: | A novel method of the production of the polycrystalline iron fiber is introduced in this paper. On the basis of the theory of pyrolysis of carbonyl and the magnetic, the information of the peculiar structure of the carbonyl iron particles is analyzed, and the growth process of the fibers is discussed. According to the theory, a set of devices is designed, and the micro size fibers are manufactured successfully. |
