title: Stages of xylene transforming during carbon particle synthesis.
abstract: Xylene is one of the materials that could be used for synthesis of different carbon nanoparticles including perfect carbon spheres with diameters of 1 to 8 microm and ellipsoids. Its changes in the course of the pyrolytic process in a hermetically sealed stainless steal container have been examined by stopping the process at different stage of temperature treatment from 100 degrees C to 600 degrees C. The prepared material is in a liquid phase up to 400 degrees C and its relative weight and optical transmittance changes have been measured. The origins of these changes are traced to solid micro and nanoparticles and their morphology, which was studied by Scanning (SEM) and Transmission Electron Microscopy (TEM), X-ray diffraction (XRD), Electron Probe X-ray Micro Analysis and Energy Dispersive X-ray Spectrometry (EDS), and Fourier Transform Infrared Spectroscopy (FTIR).
