Papers by Keyword: Si/SiC Composites

Abstract: The composite materials have been synthesized in situ by self-propagating high temperature synthesis (SHS) from natural precursors. The studied natural resources are ilmenite, kaolin, sand and rice husk ash. The reactions were carried out in a SHS reactor under static argon gas at the pressure of 0.5 MPa. The standard Gibbs energy minimization method was used to calculate the equilibrium compositions of the reacting species. The composites results have been characterized by scanning electron microscope (SEM), image analysis and X-ray diffraction (XRD). The results showed that the production of composite materials using SHS process is feasible and agree well with the thermodynamics calculations.
