silicon carbide were observed in the darker deposits. Other elements present were either in too small of concentration as compounds to be detected by XRD, substitutional in the identified phases, or present as amorphous phases.
Effect of Hot-Forging on Mechanical Properties of Silicon Carbide Sintered with Al2O3-Y2O3-MgO 893 Mg-Al-Y-O-C glassy phase. The grains of the hot-pressed specimens were fully wetted. The microstructure of the hot-forged specimen consisted mainly of
Silicon (Industrial grade) and Aluminum (Fluka grade). Chemical composition and physical properties of the raw materials are listed in Tables 2-6. Ferrosilicon was domestic. Its XRD pattern and rel-evant Fe-Si phase diagram are shown in Figures 1-2. The samples
Silicon carbide (SiC) is a wide-bandgap semiconductor with extreme hardness, high thermal conductivity, and high chemical stability at normal and high temperatures. Recently, much work has been focused on production of SiC one-dimensional nanostructures, such as nanofibers, nanowires, nanorods, and nanowhiskers, because of their high potential uses in the nano-mesoscopic research and in the
XRD has been used to confirm the crystallinity and epitaxial quality of the SiC film ().The structure of the film was 3C-SiC as indied by strong cubic (111) and (222) diffraction s at 35.6
SiC is Moissanite-6H structured and crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. there are three inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded to four C4- atoms to form corner-sharing SiC4 tetrahedra. There
carbon is detected by the broad background in the XRD pattern for almost all the samples. However, the degree of silicon carbide crystallization in each sample was dependent on the silica template that was used for the preparation. Mesoporous silicon carbides
