CARBONIZATION OF FERROCENE UNDER PRESSURE

Nano size iron particle/carbon materials have been synthesized through heating ferrocene and carbon precursors under pressure. The morphology and structural features of products carbonized at different temperatures, i.e., 420?℃ and 490℃?, for 6?h were compared using SEM, TEM and XRD measurements. It was found that the product carbonized at 420?℃ was mainly composed of α Fe, Fe 3C and Fe O, otherwise Fe 2.5 C was the significant product when ferrocene was heat treated at 490?ggesting the tendency of Fe C formation when the carbonization temperature increased from 420?℃ to 490?℃. These nano size α Fe and Fe C compounds, ranging in size from 50?nm to 100?nm, were uniformly dispersed when observed in the TEM.
