Fullerene, C60, has been investigated at a high pressure of 15 GPa and at a high temperature of 800°C using an octahedral anvil press. Samples retrieved after being heated to temperatures between 165 and 700°C under pressures from 10 to 15 GPa were found to be very hard, exhibiting micro-Vickers hardness ranging from 40 to 100 GPa. The hardness was governed by the pressure and temperature conditions studied as well as the duration of the high-temperature treatment. X-ray diffraction analysis and Raman scattering studies revealed that the hard products contained amorphous carbon consisting of $sp^{2}$-bonded clusters with a small persistence of unknown phase.
