摘要：

Whiskers of iron carbide encased in carbon shells have been prepared from iron(II) phthalocyanine. Solid FePc is oxygenated and then thermally treated under H-2 flow. With proper control of conditions, Fe3C free from metallic iron can be synthesized. The product was characterized with the help of Mossbauer effect spectroscopy, X-ray diffraction, X-ray absorption, and transmission electron microscopy. The iron carbide whiskers range in length from 300 to 500 nm, and their widths are approximately 100 nm. The carbon coating is uniform and about 2.7 nm wide.
