摘要：

The physical properties of recently created superhard and ultrahard carbon materials synthesized from pure C-60 in the pressure range 8-13 GPa and the temperature range 600-2100 K were studied. These properties are the specific gravity, specific heat in the range 400-600 K, sound velocities, elastic moduli, electrical properties, resistance to uniaxial stress and stability against oxidation. These properties are different from those of diamond and other carbon forms. The hardness of ultrahard fullerites exceed the hardness of diamond. The structures of the samples are described on the basis of X-ray data.
