i Heard a fact :

 

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

 

IS it true ???

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."
