Using quenching of samples to ambient conditions, we have studied structural transformations of fullerite C<SUB>60</SUB> upon heating at P=12. 5 GPa, i. e., in the pressure range corresponding to the regime intermediate between collapses of fullerite C<SUB>60</SUB> into the pure sp<SUP>2</SUP> and sp<SUP>3</SUP> amorphous carbon phases. A complicated picture of transformations, including the gradual crystal-to-amorphous transition with increase of the number of sp<SUP>3</SUP> atomic sites (due to the 3D polymerization) and formation of graphitic clusters with the subsequent crystallization of diamond and graphite nanocrystals, was observed.
