Ultra-hard semiconductor amorphous carbon bulk material and method for preparing the same

摘要

An ultra hard semiconductor amorphous carbon bulk material and a method for preparing the same. SOLUTION: (1) a step of preforming C60 fullerene into a columnar preform, and (2) a step of placing the obtained columnar preform in a hexagonal boron nitride crucible and placing it in a high temperature and high pressure assembly block ( 3) placing the assembly block in a high-temperature high-pressure synthesis facility and performing high-temperature high-pressure treatment; and (4) obtaining a super-hard semiconductor amorphous carbon bulk material after the treatment is completed. Preparation method. The above-mentioned preparation method uses C60 fullerene powder as a raw material, utilizes a high temperature and high pressure test, and adjusts and controls the relationship between temperature and pressure to search for a phase transition action of C60 fullerene under high pressure to obtain high hardness or It has a wide application foreground by synthesizing a dense, semiconducting amorphous carbon bulk material with ultra-high hardness.
