Rock tuler grit is a man-made silicon carbide abrasive. It is inexpensive, extremely hard, and crushes into sharp, angular particles. These properties make it an effective abrasive for cutting, shaping, and smoothing rocks and other hard materials.
For example, bo-ron fiber can be coated with boron carbide and silicon carbide reaction barriers to prevent diffu-sion and chemical reactions with the matrix that decrease the strength of the composite. Alumina fibers can be given a surface coating of silica to .
Epitaxial graphene growth on silicon carbide (SiC) by thermal decomposition is a methods to produce large-scale few-layer graphene (FLG).Graphene is one of the most promising nanomaterials for the future because of its various characteristics, like strong stiffness and high electric and thermal conductivitiy.

Benefits of SiC are described and example NASA Programs and Projects desiring this technology are given. The current status of the radiation tolerance of silicon carbide power devices is given and paths forward in the effort to develop heavy-ion single-event effect hardened devices indied.
Silicon carbide has significant advantages over silicon; it has greater chemical resistance and can therefore be used for biological appliions, for example, without any additional coating required.
For example, there is a growing amount of it —the United Nations found that people generated 44.7 million metric tons of e-waste globally in 2016, and expected that to grow to 52.2 million
For example, Yuri and Hisamatsu suggested that silicon carbide ceramics will be recessed about 3 mm under gas turbine conditions at 1523 K for 10,000 hours . Hence on the appliion of silicon carbide and its composites for gas turbine hot sections component, an oxidation-corrosion resistance environmental barrier coating (EBC) layer is required.
"Silicon carbide, on the other hand, possesses excellent mechanical strength, chemical inertness, thermal durability and electrical stability due to its unique electronic structure. "Thus it holds promise as the material for high performance sensors in, for example, deep-oil and coal mining, coustion engines, energy conversion devices and so on.
GE and its industrial businesses, led by Aviation, continue to aggressively develop next-generation silicon carbide for new appliions. The business offers electrical power products with power levels from kilowatts to megawatts for harsh environments in aerospace, industrial, and military appliions.
The interior of the fiber element was composed of sintered β-silicon carbide crystal without an obvious second phase at the grain boundary and triple points. This material showed high strength (over 600 megapascals in longitudinal direction), fibrous fracture behavior, excellent high-temperature properties (up to 1600°C in air), and high thermal conductivity (even at temperatures over 1000°C).

3300 presolar silicon carbide (SiC) grains extracted from the Murchison meteorite. SiC is the best-studied presolar phase in meteorites. For example, 28Si or 12C images, or both, are usually acquired to identify SiC grains in meteoritic acid-resistant residues
For example, the switching frequency of an electric drive is determined by the required output frequency to the motor. Furthermore, other factors such as the resonance behaviour of the entire system, electromagnetic compatibility (EMC) and heat management play an important role in defining the switching frequency to be used.
Abstract Photonic nanocavities with high quality (Q) factors are essential components for integrated optical circuits.The use of crystalline silicon carbide (SiC) for such nanocavities enables the realization of devices with superior properties. We fabrie ultrahigh-Q SiC photonic crystal nanocavities by etching air holes into a 4H-SiC slab that is prepared without using hydrogen ion
