19/6/2003· XRD patterns of the silicon carbide samples made in the control experiment (a) and in a typical experiment (b). The X-ray diffraction s in the low-angle region are usually employed to verify the long-range ordering of the mesopores in mesoporous materials, such as MCM-4l [24] .

XPS and XRD study of crystalline 3C-SiC grown by …

5/5/1999· Abstract. Preliminary XPS and XRD studies of the 3C-SiC polycrystals (with the grain size of order of 100 μm) grown by the sublimation method were performed. The XRD data proved a dominant 3C-SiC structure accompanied by an admixture of the residual 6H-SiC phase. The main core-level photoelectron spectra were analysed in detail.

Silicon carbide growth on the tungsten particulates results in the development of a wart-like morphology on the fibre surface. An understanding of this mechanism enabled minor modifiions to reactor conditions, which prevented W oxide particulate formation and greatly reduced the occurrence of such growth anomalies.
