Silicon-Based Materials from Rice Husks and Their …
Rice husk (RH) has now become a source for a nuer of silicon compounds, including silicon carbide, silica, silicon nitride, silicon tetrachloride, zeolite, and pure silicon. The appliions of such materials derived from rice husks are very comprehensive. The methods of synthesizing these silicon-based materials from RHs and their appliions are reviewed in this paper.
