PROPERTIES AND PHASE COMPOSITION OF DETONATION NANODIAMONDS SURFACE

The characteristics, properties and phase composition of surface of nano- and micro-diamond crystals obtained by detonation synthesis were researched. In blend composition of nano diamonds the carbine presence was revealed. On the surface of the nano diamond mi-crocrystals and after chemical treatment the presence of sp2 and sp3 carbon phases with the predominant content of sp3crystal phase was revealed. Together with that the presence on the surface of the sp3 amorpohous phase was established for nano diamonds.

Key words: detonation synthesis, carbon phase composition, detonation nanodiamonds, micro-diamonds, X-ray diffraction, electron microscopy, Raman scattering

SIMULTANEOUS THERMAL ANALYSIS AND RAMAN SPECTROSCOPY AS COMPLEMENTARY METHODS OF DIAGNOSTICS OF CARBON ALLOTROPIC FORMS

Work is devoted to detection of distinctive characteristics of allotropic forms of car-bon which would provide their identification from mixes. The complex analysis is offered by methods: the synchronous thermal analysis with studying of composition of the emitted gases and Raman spectroscopy. It was shown that researches of carbon structures and their mixes by the declared methods agree well and complement each other.

Key words: carbon allotropic modifications, synchronous thermal analysis, Raman spectroscopy, carbon nanotubes, purity assessment, properties characterization
