Thermal Transformations of Soot-Like Structures

Depending on the appHed temperature, products of the most different kinds are obtained from heating arc furnace black in metal tubes. The structures formed at 

A dose electron microscopic inspection of carbon black shows the single soot partides to contain one or more nudeation centers that, in part, exhibit an onion- 

The stmcture of products from sooting benzene/oxygen flames has also been studied in this context. It turned out that the sooty film precipitating on the cool parts of the apparatus consists of tubular and onion-like carbon species. Still the product obtained is rather inhomogeneous, so for the time being, combustion methods are no effective means of generating carbon onions.
