We have studied the 3D polymerization of fullerite C₆₀ under high pressure by x-ray diffraction, Raman spectroscopy, measurements of hardness, and annealing experiments. For the first stage of this gradual transformation we have proposed the model, in which the 3D polymers may involve both bonding characters of van der Waals and covalent intermolecular bonds. The pressure of the crossover between 2D and 3D polymerization was estimated near 8 GPa.
