Effect of ultrasound treatment of C60 solutions on the crystalline structure of precipitated fullerite

The structure of fullerite precipitated from solutions of C60 in toluene, chlorobenzene, and 1,2-dichlorobenzene by adding isopropanol was studied. It was demonstrated that, irrespective of the nature of the solvent, the parameter of the fcc lattice of precipitated fullerite decreases markedly when the process occurs in the presence of a ultrasound field. No effect of ultrasound sonication on the size of the precipitated crystallites was observed.
