| Abstract: | New information is presented on the structure and growth of carbon filaments formed in association with catalytic metal or metal carbide particles during pyrolysis of natural gas. The structures of the filaments and of the particles have been examined by transmission electron microscopy. The filaments are hollow, ~0.1 μm or less in diameter, and vermicular as opposed to straight. The graphite basal planes are frequently not parallel to the axis of the filament. Individual catalyst particles have been identified as (Fe,Cr)23C6 when pyrolysis occurs in a stainless steel tube and as γ-iron in a plain carbon steel tube. |
