Hihg Pressure Synthesis, Structure, Physical and Mechanical Properties of C_<60> Fullerite Superhard and Ultrahard Phases
New data on the synthesis conditions, structure and physical properties of the superhard and ultrahard samples created from solid C60 by static high-pressure high-temperature treatment in the range of 9. 5-13 GPa ; 600 -2100 K are represented. Measured velocities of the compressional sound waves in the ultrahard fullerites exceed the highest values for diamond. Bulk elastic modulus for the hardest fullerite samples more than twice exceeds that of diamond. Ultrahard fullerite tip is applied for measurements of hardness of diamond and fullerites. Maximum hardness of fullerite is measured to be 310±40 GPa.
