RH contain higher amount of carbon and silicon, which is an ideal source for the production of Silicon carbide (SiC). The aim of this work is to prepare SiC powder from rice husks (RH) by simple synthesis route. Silicon carbide is an important non-oxide ceramic which has diverse industrial applications. It is reinforced with metal matrix composite shows better mechanical properties.
In this investigation, acid leached rice husk was sintered at inert gas atmosphere using tubular furnace to obtain silicon carbide. The obtained SiC powder was characterized by using SEM-EDS, FTIR and XRD. The morphology and elemental composition of the samples were performed by SEM with EDS and structural determination by FTIR spectrum and X-ray diffractogram.
