“…Another approach is to create a plasma to obtain the decomposition of a precursor that can be gaseous, liquid or solid. Different groups around the world have developed such techniques, using different types of precursors (SiO 2 + CH 4 , Si anode + CH 4 , coarse SiC...) or plasma source (transfer arc, DC or RF thermal plasma...) [19][20][21][22][23][24][25]. One of the tricky parts concerning the use of powders as a precursor is to manage to introduce the powder inside the dense plasma.…”

In the growing field of nanomaterials, SiC nanoparticles arouse interest for numerous applications. The inductively coupled plasma (ICP) technique allows obtaining large amount of SiC nanopowders from cheap coarse SiC powders. In this paper, the effects on the SiC structure of the process pressure, the plasma gas composition, and the precursor nature are addressed. The powders were characterized by X-ray diffraction (XRD), Raman and fourier transform infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM) and high resolution electron microscopy (HREM), chemical analyses, BET and photon correlation spectroscopy (PCS) measurements. Whatever the precursor (a-or b-SiC), the nanoparticles were crystallised in the cubic b-SiC phase, with average sizes in the 20-40 nm range. Few residual grains of precursor were observed, and the decarburization due to the reductive Ar-H 2 plasma lead to the appearance of Si nanograins. The stoichiometry of the final product was found to be controllable by the process pressure and the addition of methane.

“…In order to obtain high performance SiC ceramics, several alternative methods have hence been proposed for the synthesis of high purity and selected quality powder over the last decades. Among these, the most  common methods are: physical vapor transport (PVT) technique, chemical vapor deposition (CVD), self-propagating high temperature synthesis (SHS), sol-gel, microwave, and plasma driven reactions [6][7][8][9][10][11][12]. In addition, special attention was given in recent years towards synthesis of nanosized SiC powder to allow the production of high performance products like structural components.…”

Sintering and mechanical properties of β‐SiC powder obtained from waste tires

Plasma synthesized SiC powder obtained from quartz and carbonaceous residue of waste tires was successfully sintered at 1925 ℃ by pressureless liquid-phase method using yttria and alumina as sintering aids (T-SiC). Comparison with sintered SiC obtained from commercial powder (C-SiC) put in evidence of similar sintered density (98%T.D.), but much finer microstructure of T-SiC than that of C-SiC. T-SiC also showed higher flexural strength than C-SiC both at room temperature (508 vs. 458 MPa) and at 1500 ℃ (280 vs. 171 MPa). Difference in liquid phase was responsible for the differences in hardness and fracture toughness. The high value of the Young's modulus of T-SiC (427 MPa) confirmed the high degree of sinterability of this powder and that it can be a promising candidate for structural applications with high added value.
