摘　　要：人造金刚石合成机理的研究符合发展新质生产力的内在要求,可以高效指导优质金刚石晶体材料的制备,特别是对合成边界条件的预测和探究,形核和长大过程的控制,性能的调控和修饰等具有重要作用。本文就目前金刚石合成方法中的高温高压法、爆轰法、气相沉积法的相关合成机理进行详细的阐述,以期对金刚石的合成过程有更加深入的了解。由于目前的技术条件无法对合成过程进行直接实时观察,对人造金刚石的合成机理暂未形成统一的认识,上述理论研究方法主要通过对实验过程和合成前后产物的分析进行推理。笔者认为借助于分子动力学等方法进行模拟仿真,同时利用原位测量设备如原位X射线进行实时监测,结合合成过程中的其他表征,未来有望进一步揭示人造金刚石合成的本质。The research on the synthesis mechanism of artificial diamonds meets the inherent requirements of developing new quality productive forces and can efficiently guide the preparation of high-quality diamond crystal materials,especially in predicting and exploring synthesis boundary conditions,controlling nucleation and growth processes,and regulating and modifying properties.In order to have a deeper understanding of the diamond synthesis process,this article provided a detailed explanation of relevant synthesis mechanisms of high-temperature and high-pressure method,detonation method,and vapor deposition method used in diamond synthesis.Due to the limitations of current technological conditions,direct real-time observation of the synthesis process is not possible,and there is currently no unified understanding of the synthesis mechanism of artificial diamonds.The above theoretical research mainly relies on the analysis of experimental processes and products before and after synthesis.The authors believed that with the help of molecular dynamics and other methods for simulation,the use of in-situ measurement equipment such as in-situ X-ray for real-time monitoring,and consideration of other characterizations during the synthesis process,it is expected to further reveal the essence of artificial diamond synthesis in the future.
