• Ultra-fine iron particles were dispersed in a glasslike carbon matrix by the heat treatment of acetylferrocenefurfural resins. The dispersed iron particles were investigated by means of X-ray and electron diffraction analyses and by means of electron microscopy. In resins heat-treated at 400 °C, iron particles of varying diameters were observed by means of electron microscopy. The crystal structure of the iron particles was analyzed by means of X-ray and electron diffractions. Finely subdivided iron particles were identified as hexagonal, close-packed (hep) and expanded, body-centered cubic (bec) irons. The hep iron is the high-pressure phase of iron metal. The ultra-fine iron particles were coagulated to larger particles by heat treatment above 400 °C. The size of their unit cell was the same as that of standard bec iron.
