The spectral analisys of structure of ultradispersed diamonds
<i>The results of research into the structure of ultradispersed diamonds (UDD) are offered. Based on X-ray analysis and Raman spectra, the presence of diamond crystal phase in the UDD particles is found. In the Raman spectra, the sp</i><sup><i>2</i></sup><i>- and sp</i><sup><i>3</i></sup><i>-hybridized carbons show up as well. The analysis of infrared absorption spectra makes it possible to conclude that the composition of functional groups present in the particles changes in the course of the treatment.</i>
