From Analysis of the Structure of Ultrafine Diamond to the Problem of Its Formation Kinetics

摘要

The formation kinetics of ultrafine diamond samples produced by detonation synthesis is inferred from infrared and ultraviolet absorption spectra.The results of experiments have shown that ultra-fine diamond (UFD) [1,2] produced by detonation synthesis is characterized by structural heterogeneity.The density,element composition,high contents of functional groups,and the other parameters of UFD differ considerably from the corresponding characteristics of traditional diamond [3-9].Therefore,UFD is treated differently:as a diamond-like phase of carbon [4],a hy-permolecular system [6],and a composite material [5].
