| Abstract: | 60 in the pressure range and the temperature range were studied. These properties are the specific gravity, specific heat in the range , 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.
