The industrial use of fullerenes will require a significant up-scaling
of their production. The five actually known techniques are discussed
: 1. The electric are (Kratschmer-Huffman). 2. The vaporization of car
bon by pulsed lasers. 3. The direct vaporization of carbon in focused
sunlight. 4. The direct inductive heating of carbon. 5. Sooting hydroc
arbon flames. The difficulty of up-scaling the electric are set-up bec
ause of the photochemical destruction of fullerenes will be demonstrat
ed. The use os sooting hydrocarbon flames for an industrial production
of fullerenes is suggested.
