Microstructural Phase Characterization of Multiwalled Carbon Nanotubes/Quartzite Nanocomposite

Yusuf Tijjani, Maharaz Mohammed Nasir

Abstract


The effects of the addition of multiwalled carbon nanotubes (MWNTs) on microstructural phase properties; peak geometric parameters, crystallite size and residual quartz of sintered MWNTs-quartzite ceramic nanocomposite are determined. MWNTs reinforced quartz ceramic nanocomposite pellets were fabricated by modified conventional powder processing involving pressureless sintering method. The sintered nanocomposite pellets were then prepared and subjected to XRD microstructural technique for comprehensive phase analysis. It has been observed that the crystal properties; peak intensity, FWHM broadening and crystallite size have no effect on the densification property of 1 wt. % MWNTs-quartzite Nano composite. Thus, its thermo-mechanical properties have been influenced by the MWNTs acting as sintering aid mineralizer to convert the residual quartz to tridymite.
