Abstract:
A hard carbon material having a density greater than 2.3 g/cm3 and a hardness from 1.0 Gpa to 50 Gpa formed by the process of:a) providing a fullerene based carbon powder comprising at least 99% single walled nanotubes, b) agglomerating said fullerene based carbon powder to a density above 1.4 g/cm3; c) subjecting said fullerene based carbon powder to a pressure of 1.0 to 10.0 Gpa, a temperature of from 300-1000Â° C. for a period of time from 1 to 10000 seconds.
