AB  - Since the successful synthesis of bulk sp3 amorphous carbon in 2021, this material has attracted considerable attention owing to its ultrahigh hardness, mechanical isotropy, potential for shaping and machining, and distinctive electronic structure. These features make it a promising candidate for applications in ultra-precision machining and optoelectronic detection. Recent studies have mainly focused on the formation mechanism, thermodynamic stability, structural and property regulation, and synthesis process optimization of sp3 amorphous carbon materials derived from fullerenes under high-pressure and high-temperature conditions. These studies have not only deepened the understanding of the formation mechanism of sp3 amorphous carbon, but also promoted the further development of its functional applications. This review systematically summarizes the relevant research progress and discusses future key directions, including the large-size and high-quality synthesis, precision shaping, and functional application expansion of sp3 amorphous carbon.
