The XRD pattern for the sintered ceramic composite samples are presented in Figure 1 to 3 and Table 1, which shows the addition of 5:3 vol.% SiC and TiO 2 respectively,represented as sample D. Figure 4 shows the SEM/EDS data of the samples sintered at
The Si peaks shown in the XRD pattern were used for calibration. First, Fig. 7 a and 7b indie that the Al 2 O 3 peaks for sample 1 shifted to lower angles than those for ALO. For pure ALO, the pure alumina powder was hot pressed at 1400˚C, while for sample 1, the fluidized powder was pre-sintered at 1000 ˚C before the hot pressing at 1400 ˚C.

Elemental silicon has a wide range of traditional appliions in metallurgy, synthesis of silicone, and in the semiconductor industry. Nanostructured silicon materials, because of their unique properties and small size, have promising appliions in a range of new technologies, such as nanoelectronics 11 , photonics 12 , biotechnology 13 , 14 , 15 , energy harvesting 16 , 17 , 18 , and

Powder X-ray Diffraction (XRD) is one of the primary techniques used by mineralogists and solid state chemists to examine the physico-chemical make-up of unknown solids. This data is represented in a collection of single-phase X-ray powder diffraction patterns for the three most intense D values in the form of tables of interplanar spacings (D), relative intensities (I/I o ), and mineral name.
