Composites of SiC/Si and SiC/SiC were prepared from single yarns of SiC. The use of carbon coatings on SiC yarn prevented the degradation normally observed when chemically vapor deposited Si is applied to SiC yarn. The strength, however, was not retained when the composite was heated at elevated temperatures in air. In contrast, the strength of a SiC/C/

From graphene to silicon carbide: ultrathin silicon carbide flakes
Nanotechnology, 2016This study presents a new ultrathin SiC structure prepared by a catalyst free carbothermal method and post-sonication process. We have found that merging ultra-light 3D graphene foam and SiO together at high temperature leads to the formation of a complex SiC structure consisting of 3D SiC foam covered with traditional 1D nanowires.

There exists a need, especially in the cases of some military applications, for a stable, high-temperature semiconductor material. Active and passive devices fabricated from such a material could operate in a high-temperature ambient and simultaneously resist radiation damage.

A process is described for forming silicon carbide coatings on nickel based superalloys by: i) nitriding the alloy or depositing a titanium nitride film on the alloy by reactive sputtering; ii) vapour phase chemica deposition of a thin film of titanium nitride; iii) annealing in a nitrogen and hydrogen atmosphere; iv) vapour phase chemical deposition ...

Silicon carbide microdisk resonator
Optics Letters, 2013We demonstrate a silicon carbide (SiC) microdisk resonator with an intrinsic optical quality factor of 6.19×10(3), fabricated on the 3C-SiC-on-Si platform. We characterize the temperature dependence of the cavity resonance and obtain a thermo-optic coefficient of 2.92×10(-5)/K for 3C-SiC.

Silicon Carbide Monofilament‐Reinforced Silicon Nitride or Silicon Carbide Matrix Composites
Journal of the American Ceramic Society, 1989SiC‐monofilament‐reinforced SiC or Si 3 N 4 matrix composites were fabricated by hot‐pressing, and their mechanical properties and effects of filaments and filament coating layers were studied.
