- Title
hardest amorphous material.

- Abstract
The term "glassy carbon" often encountered in literature is not an accurate expression, since "glassy carbon" does not exhibit glass transition during cooling or heating. In contrast, amorphous materials can be referred to as disordered, and include gels, amorphous carbon and silicon, defect-rich solids, and melt-quenched (MQ) glasses, since their microstructure is disordered in the long range (i.e. beyond the scale of ca. 2 nm). They created a new phase of amorphous carbon (AM carbon), namely, AM-III, via relaxation of compressed fullerene C SB 60 sb , under a pressure of 25 GPa and a heat-treatment temperature of ~1200°C.
