“…This result also shows good consistency with the XRD pattern of SiCNTs synthesized at 40 and 60 min in Figure 2(b) and 2(c). Similar absorbance bands corresponded to Si-C stretching bond of SiC nanowires also were reported by Zhang et al (2015), in which the strong absorption band of the Si-C stretching band was observed at 795 cm -1 in the FTIR spectra.…”

“…The broad absorption band at around 3430 cm −1 shows a negligible Si–OH (silanol) peak, indicating that the surface modification causes the SiC surface to produce some silanols, which are relatively hydrophilic [ 47 ]. The peak at around 1570 cm −1 is due to the absorbed water [ 36 , 48 ]. Therefore, it can be inferred that the submicron powder produced consist mainly of SiC.…”

This paper presents the design, development and realization of a fast and novel process for the synthesis of 3C silicon carbide (β-SiC) nanorods and submicron powder. Using SiO2 (or Si) and activated carbon (AC), this process allows β-SiC to be synthesized with almost 100% purity in timeframes of seconds or minutes using multimode microwave rotary tube reactors under open-air conditions. The synthesis temperature used was 1460 ± 50 °C for Si + AC and 1660 ± 50 °C for SiO2 + AC. The shortest β-SiC synthesis time achieved was about 20 s for Si + AC and 100 s for SiO2 + AC. This novel synthesis method allows for scaled-up flow processes in the rapid industrial-scale production of β-SiC, having advantages of time/energy saving and carbon dioxide emission reduction over comparable modern processes.

“…Similar with Bi et al 25 in their study synthesis of SiC/MWCNTs hetero-structures, they reported that the highest formation of SiCNTs was obtained from blend of SiO 2 particles and MWCNTs in the ratio of 1:3. Furthermore, Zhang et al 23 in their study of molten salt assisted synthesis of 3C-SiC nanowires also reported that blend of SiO 2 particles and carbon in the ratio of 1:3 has showed the presence of XRD peak corresponded to β-SiC with highest intensity and indicated the high yield formation of SiC nanowires.…”

“…In the previous study, several researchers have investigated the effect of ratio of raw material on the synthesis of SiC nano-material 22,23 . For example, Ding et al 24 in their study synthesis of SiC nanowires by using molten salt synthesis (MSS) method at temperature of 1400 °C indicates that ratio of raw materials is an important factor to synthesize SiC nanowires and they revealed that intensity of β-SiC peaks of ratio 1:3 was higher compared to Si and salts containing carbon of ratio 1:1, 1:2 and 1:4 which suggested that formation of SiC nanowires was highest when Si and salts containing carbon of ratio 1:3 was used.…”

Silicon carbide nanotube (SiCNTs) has been proven as a suitable material for wide applications in high power, elevated temperature and harsh environment. For the first time, we reported in this article an effective synthesis of SiCNTs by microwave heating of SiO 2 and MWCNTs in molar ratio of 1:1, 1:3, 1:5 and 1:7. Blend of SiO 2 and MWCNTs in the molar ratio of 1:3 was proven to be the most suitable for the high yield synthesis of β-SiCNTs as confirmed by X-ray diffraction pattern. Only SiCNTs were observed from the blend of MWCNTs and SiO 2 in the molar ratio of 1:3 from field emission scanning electron microscopy imaging. High magnification transmission electron microscopy showed that tubular structure of MWCNT was preserved with the inter-planar spacing of 0.25 nm. Absorption bands of Si-C bond were detected at 803 cm -1 in Fourier transform infrared spectrum. Thermal gravimetric analysis revealed that SiCNTs from ratio of 1:3 showed the lowest weight loss. Thus, our synthetic process indicates high yield conversion of SiO 2 and MWCNTs to SiCNTs was achieved for blend of SiO 2 and MWCNTs in molar ratio of 1:3.
