1. A method for preparing a millimeter-sized bulk sp3 amorphous carbon material, comprising a step of
performing a high-temperature and high-pressure (HTHP) treatment on a sample of C60 powder in a Walker-type large-volume press at a temperature of 900-1000° C., and a pressure of 27 GPa, so as to obtain the millimeter-sized bulk sp3 amorphous carbon material.
