Formation of SiC from rice husk silica-carbon black mixture: Effect of rapid heating

Review on the physicochemical treatments of rice husk for production of advanced materials

“…On the other hand, if the gas flow rate is too slow, most of the CO gas will be concentrated at the reaction zone and thus inhibiting the reaction to form SiC. In addition, fast moving gases can also destabilize the liquid droplet at the whisker tip and hinder whisker growth [180,215]. The effect of the atmosphere used during pyrolysis,i.e.…”

Steam gasification of tyre waste, poplar, and refuse-derived fuel: A comparative analysis

“…In terms of economy and efficiency, the carbothermal reduction is the best choice. It involves inexpensive silicon dioxide and carbon (or carbon precursors) as the starting materials (Krstic, 1992;Wei, 1983;Krishnarao and Subrahmanyam, 1996), according to the following overall reaction: SiO 2 ðsÞ þ 3CðsÞ () SiCðsÞ þ 2COðgÞ…”

Growth of SiC whiskers from hydrogen silicone oil

“…Through the crack deviation, whisker bypass and extraction mechanism, SiC whiskers could improve the quality of ceramic coating [4,5]. Up to now, many preparation methods of SiC whiskers have been reported, such as thermal processing of natural carbon-and silica-containing natural materials [6][7][8][9], electrospinning [10], the chemical vapor deposition (CVD) technique [11], shape memory synthesis over CNTs [12,13] or activated carbon [14] and so on. However, above mentioned methods cannot give consideration to the low cost and free purification.…”
