“…Plasma processing was carried out by non-transferred arc thermal plasma reactor as reported in our previous work [21, 23]. The milled SiC powder was fed into the plasma arc through the internal feeding pipeline of 2-mm inner diameter in the plasma torch using a specially designed powder feeder.…”

“…For example, nanopowders primarily due to the higher specific surface areas and surface activities can provide the low-temperature sinterability of nano-sized SiC in the consolidation processing and the improvement of mechanical properties by making it possible to reach high densities [22]. Therefore, in present, we have developed a new method to prepare Si-coated SiC (Si-SiC) nanoparticle to apply as a sintering additive by using non-transferred thermal DC plasma processing of solid-state synthesized SiC powder [23]. …”

The Si-coated SiC (Si-SiC) composite nanoparticle was prepared by non-transferred arc thermal plasma processing of solid-state synthesized SiC powder and was used as a sintering additive for SiC ceramic formation. Sintered SiC pellet was prepared by spark plasma sintering (SPS) process, and the effect of nano-sized Si-SiC composite particles on the sintering behavior of micron-sized SiC powder was investigated. The mixing ratio of Si-SiC composite nanoparticle to micron-sized SiC was optimized to 10 wt%. Vicker’s hardness and relative density was increased with increasing sintering temperature and holding time. The relative density and Vicker’s hardness was further increased by reaction bonding using additional activated carbon to the mixture of micron-sized SiC and nano-sized Si-SiC. The maximum relative density (97.1%) and Vicker’s hardness (31.4 GPa) were recorded at 1800 °C sintering temperature for 1 min holding time, when 0.2 wt% additional activated carbon was added to the mixture of SiC/Si-SiC.

“…[16][17][18][19][20][21][22][23][24] Such the ICTP method has also actively been tested for synthesizing Si-based nanomaterials for anode material in LIB, including carbon-coated Si nanoparticles, Si/C nanocomposites, etc. [25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40] On the other hand, we have developed a novel technique of the PMITP+TCFF method for high rate production of nanoparticles. [41][42][43][44][45][46][47][48] The pulse-modulated induction thermal plasma (PMITP) is the PMITP, which is sustained by amplitude-modulated coil current.…”

Graphite-coated silicon nanoparticles were synthesized using pulse-modulated induction thermal plasma (PMITP) with a time-controlled feedstock feeding (TCFF) method at high production rates. The PMITP+TCFF method is a high production method of nanoparticles with a high feedstock feeding rate of several g min−1. Micro-sized silicon powder as feedstock was injected synchronously into Ar/H2 PMITP to be evaporated completely. Argon/CH4 gas mixture was introduced as a quenching gas and a carbon source from three different downstream portions for comparison. As a result, graphene-encapsulated Si nanoparticles were successfully synthesized with Ar/CH4 gas mixture injection from adequate downstream port.
