N2 - Gas-antisolvent (GAS) process using CO2 successfully prepared crystals of fullerene (C60) from a toluene solution through a precipitation. Particle sizes of precipitated C60 could be easily controlled by changing the initial pressurization rate of CO2, the temperature at the initial pressurization, and the quantity of C60. Fullerene particles obtained by GAS method had regular octahedral shapes, whereas the particles obtained by adding liquid ethanol as an antisolvent to C60 solution did not have such shape. Particle sizes could be changed in a range of 1.0-8.5 μm by GAS method; they were wider than the range of particles obtained by ethanol addition (0.7-1.8 μm).
