D. Laplaze et al., PRODUCTION OF FULLERENES FROM SOLAR-ENERG Y - THE ODEILLO EXPERIMENT, Comptes rendus de l'Academie des sciences. Serie 2, Mecanique, physique, chimie, sciences de l'univers, sciences de la terre, 318(6), 1994, pp. 733-738
The high concentration of solar radiation, obtained with the Odeillo S
olar Furnace facilities, is used to vaporize graphite in a rarefied he
lium atmosphere. We show that the soot obtained contains C60, C70 and
other heavier molecules. We discuss the possibility of using this tech
nique, which can be improved on, to replace the usual process involvin
g an electric arc between two graphite electrodes.
