Shock-wave synthesis of diamond from C{sub 60}-C{sub 100}-fullerene powder was first accomplished by using the explosive compaction technique with plane wave loading in the pressure range of 24-40 GPa. The compacts of various initial composition comprised diamond, FCC C{sub 60}-fullerite, graphite, and amorphous carbon. The largest diamonds of 0.1-1.0 {mu}m were obtained under shock loading of pellets consisting of copper powder with 5 wt.% fullerite at 24 and 38 GPa, and pellets consisting of copper powder with 10 wt.% fullerite at 40 GPa. The end product consists of diamond without intermediate diamondlike phases such as n-diamond and hexagonal diamond (lonsdaleite).
