Abstract: We present an analytical bond-order potential for silicon, carbon, and silicon carbide that has been optimized by a systematic fitting scheme. The functional form is adopted from a preceding work [Phys. Rev. B 65, 195124 (2002)] and is built on three independently fitted potentials for Si …

The differences in nature of organic matter in raw rice husks (RRH) and coked rice husks (CRH), and their effect on silicon carbide synthesis have been studied by means of infrared spectroscopy and X-ray diffractometry, so that the benefit of RH structure is fully exploited. Both RRH and CRH can be used as precursors for SiC synthesis, although different reaction kinetics and thus different
