Using high-pressure-high-temperature treatment of fullerites it is possible to prepare new carbon materials, including polymerized fullerites, amorphous carbon, and nanocrystalline diamond-plus-graphite composites. We have studied the mechanical properties (hardness, Young modulus, fracture toughness coefficient) for some of new phases. The interrelationship between hardness and density, established for the fullerite-based carbon phases, is in good accordance with the corresponding data for amorphous carbon.
