Silicon Carbide whiskers have been synthesized using silica sol and activated carbon as reagents via microwave heating without the presence of any of the alysts, such as Fe, Ni, and Al etc.. The synthesized whiskers were separated and concentrated from the as‐synthesized products using the gravity concentration process.
The electromagnetic (EM) wave absorption properties of 2-mm-thick silicon carbide nanowire (SiCNW)−epoxy composites were studied in the range of 2−40 GHz using a free-space antenna-based system. The 35 wt % SiCNW composites exhibited dual-frequency EM wave absorptions of −31.7 and −9.8 dB at 8.3 and 27 GHz, respectively. The minimum reflection loss of −32.4 dB was achieved at …

New ceramic is super-tough Heat-dissipation properties of electronic packaging materials can be improved with a coination of aluminum nitride particles and silicon carbide whiskers , according to a paper presented by Lin Li and D.
2016/3/2· In this study, aluminium-silicon carbide (Al-SiC) metal matrix composites (MMCs) of different compositions were prepared under different compaction loads. Three different types Al-SiC composite specimens having 10%, 20% and 30% volume fractions of silicon carbide were fabried using conventional powder metallurgy (PM) route.
894 A K Ray et al 2. Experimental procedure The four-point bend specimens were sliced, prepared, surface finished and randomized from a 150 mmx 50 mm x 12.5 mm preformed billet of 25 wt% silicon carbide whisker reinforced alumina
Recent studies showed that the addition of ceramic whiskers significantly reinforced resin composites. The aim of the present study was to use a silicon carbide whisker-silica particle mixture to reinforce resin composites, and to investigate the effect of heat-treatment temperature and duration of the whisker-silica mixture on composite properties.

Traditionally, pump manufacturers used SiC (silicon carbide) for bushings and bearings in these pumps because of its high hardness and ability to withstand abrasive wear in solid media. Since the early 1980s, OEM pump manufacturers have been using sintered SiC bearings for the stationary and rotating components of tubular casing pumps.

In the early 1980s, researchers at Oak Ridge National Laboratory developed a new type of ceramic composite reinforced with dispersed silicon carbide (SiC) whiskers. The majorityphase (“matrix”) material of these composites was aluminum oxide (Al2O3) and the minority-phase (“filler”) SiC was grown in whisker-form by a pyrolysis technique using organic waste such as rice hulls. Inclusion
The silicon reacts with the graphite in the carbon-carbon composite to become carbon-fiber-reinforced silicon carbide C/SiC. These brake disks are used on some road-going sports cars, supercars, as well as other performance cars including the Porsche Carrera GT , the Bugatti Veyron , the Chevrolet Corvette ZR1 , the McLaren P1 , [46] Bentley , …
