graphite --------> Fullerene

[chuinhen]

i Heard a fact :

 

vapourisation of graphite give rise to Fullerene !?!?!

 

IS it true ???

[chuinhen]

is there any article which talk about this ??

"Synthesis of fullerenes was first accomplished by laser sublimation of graphite in an inert gas atmosphere by Curl, Smalley and Kroto [1, 6] - Fig. 1. However, this technique did not provide for the production of gram quantities of C60. Efforts to scale-up this approach were unsuccessful and other methods were later developed. These included e.g. resistive heating (Fig. 3) or arcing (Fig. 4-6) of graphite [13-15, 23-57], combustion of hydrocarbons in sooting flames [61-71], thermal [73-76, 78-79] and non-thermal [77, 80-85] plasma pyrolysis of coals and hydrocarbons, carbon sublimation in a solar furnace - Fig. 7 [89-92] and thermal decomposition of hydrocarbons [93-97]. Those various techniques which can produce fullerenes are described in detail but the carbon electric arc approach, mastered by Krätschmer and Huffman in 1990 [14, 23], is currently the winner in the competitions for maximum production rate, cost and ease of implementation. Thus it still remains the only commercial method of fullerene production."
