Abstract

A diamond-containing material (DCM) produced by detonation was mechanically milled using KM-1 and AGO-2S mills. Experimental spectra for infrared (IR) absorption, Raman scattering and X-ray diffraction patterns (XRD) were obtained for the treated DCM samples. We compared the Raman and IR spectra for the KM-1 milled samples and concluded that the surface of the DCM particles was not uniform. The mechanical force that resulted from milling with the AGO-2S destroyed the non-diamond part of the particles and initiated irreversible physical and chemical changes in them. The destruction of the diamond grains was the consequence of these irreversible changes. It follows from the experiments that the dipole momentum of the DCM particle was caused by the presence of polar fragments of molecules. The constant dipole momentum of the particles facilitated the aggregation. Based on this, we proposed a model of a structurally inhomogeneous DCM particle.
