Silicon carbide is an attractive material for engineering and industrial applications in harsh conditions. In manufacturing process, conventional heating process is commonly used to synthesis the silicon carbide. In this study, SiC nanowhiskers were synthesized from microwave heating of mixture of graphite and silica in the ratio of 3: 1. The mixture was heated by using laboratory microwaves oven to 1400°C at heating rate of 20 °C/min and temperature was hold for 30 minutes. Photoluminescence spectroscopy and Fourier transform infrared spectroscopy were used to characterize the SiC nanowhiskers. Photoluminescence spectrum of SiC nanowhiskers showed a sharp peak at 420 nm corresponding to band gap of SiC (2.39 ev). FTIR absorption spectra of SiCNWs recorded a band at 805.22 cm-1 corresponding to Si-C bond.

Silicon carbide (SiC) is an important ceramics for engineering and industrial applications due to its advantage to withstand in high temperatures. In this article, a demonstration of SiC nanowhiskers synthesis by using microwave heating has been shown. The mixtures of raw materials in the form of pellets were heated, using a laboratory microwave furnace, to 1400°C for 40 minutes at a heating rate of 20°C/min. The characterization process proved that the mixture of graphite and silica in the ratio of 1:3 is an ideal composition for synthesizing single phase β-SiC nanowhiskers. Vapor-solid mechanism was suggested to explain the formation of SiC nanowhiskers by the proposed microwave heating.

“…And the diffraction peaks located at 35.91, 60.31, and 72.21 can be assigned to the o 111 4 , o220 4, and o3114 crystalline planes of β-SiC (ICDD No. 29-1129) [22,23]. In addition, the low diffraction peaks located at around 701 marked with an asterisk might be due to the Si substrates used in our experiments [24].…”
