“…Today, the synthesis of silicon carbide nanoparticles has become widespread among scientists around the world. There are many developed methods for the synthesis of silicon carbide nanoparticles, for example: sintering [13][14][15][16][17][18][19], combustion [20,21], selective method [22], sol-gel method [23][24][25][26], hydrothermal acid leaching [27], pyrolysis [28][29][30], pyrohydrolysis [31], low temperature synthesis [32,33], microwave synthesis [34][35][36][37], chemical vapor deposition [38][39][40][41][42], in situ growth [43,44], electric arc synthesis [45,46], etc.…”

Silicon carbide is an extremely hard material that exhibits exceptional corrosion resistance as well as thermal shock resistance. Its high mechanical properties determine the increased performance of materials based on it. The combination of high thermal conductivity and low thermal expansion coefficient determines the stability of silicon carbide at high heating rates and under stationary thermal conditions. To date, significant progress has been made in the development of methods for the synthesis of various materials based on silicon carbide. The main synthesis methods that scientists use in their research are the sol-gel method, sintering, pyrolysis, microwave synthesis, chemical vapor deposition, etc. The use of "green" techniques in the synthesis of SiC has gained wide popularity due to environmental friendliness, renewability, and ease of implementation. This review analyzes modern research in the field of silicon carbide synthesis published in peer-reviewed professional journals.

“…An environmentally friendly method of sample preparation was described by Senger et al for the determination of W in silicon carbide samples. 160 The method, termed pyrohydrolysis, occurred when sample (20 mg) was mixed with 50% hydrogen peroxide (1.2 mL) and oxygen at a flow rate of 0.1 L min −1 at a temperature of 1000 °C for one hour. The process converted the WC into volatile W species which were extracted and collected in water.…”

“…In this context, several analytical techniques have been applied [ 9 , 10 , 11 , 12 , 13 , 14 , 15 ]. The most common approach involves the dissolution of the sample followed by inductively coupled plasma mass spectrometry (ICP-MS) or ICP-optical emission spectrometry (ICP-OES) analysis [ 6 , 16 , 17 , 18 , 19 , 20 ].…”

Tackling the Challenging Determination of Trace Elements in Ultrapure Silicon Carbide by LA-ICP-MS

The goal of accurately quantifying trace elements in ultrapure silicon carbide (SiC) with a purity target of 5N (99.999% purity) was addressed. The unsuitability of microwave-assisted acid digestion followed by Inductively Coupled Plasma Mass Spectrometry (ICP-MS) analysis was proved to depend mainly on the contamination induced by memory effects of PTFE microwave vessels and by the purity levels of acids, even if highly pure ones were used in a clean environment. A new analytical protocol for the direct analysis of the solid material by laser ablation coupled with ICP-MS (LA-ICP-MS) was then exploited. Different samples were studied; the best results were obtained by embedding SiC (powders or grains) in epoxy resin. This technique has the great advantage of avoiding any source of external contamination, as grinding, pressing and sintering pretreatments are totally unnecessary. Two different laser wavelengths (266 and 193 nm) were tested, and best results were obtained with the 266 nm laser. The optimized protocol allows the determination of elements down to the sub-mg/kg level with a good accuracy level.
