FTIR ANALYSIS OF THE SURFACE OF NANOSTRUCTURED ALUMINUM NITRIDE POWDER PREPARED VIA CHEMICAL SYNTHESIS

Surface chemistry analysis of nanostructured aluminium nitride powder, obtained by a chemical synthesis method, has been conducted using FTI R spectroscopy. The study compared the spectra of the as-synthesized p owder, the activated powder treated at temperatures from 573 to 873 K, the surface-deuteriated powder, and the powder treated under ammonia. Hydroxy and amine functional groups were determined on the surface of the as-synthesized powder. The activity and the types of these groups were examined. The surface analysis results were compared with those of gamma-Al2O3. The unique surface characteristics of the nanostructur ed AlN are discussed.
