Silicon carbide is an extremely hard and long-wearing material. It can withstand harsh environments like high temperatures and pressure without succumbing to erosion or corrosion.
Carbon fibre reinforced composite materials (CFRPs) have many structural applications such as refractories, abrasives and metallurgical raw materials; semiconductor substrates; as well as being attractive options for in vivo biomedical use due to their robust chemical resistance.
High Temperature Resistance
Silicon carbide is an extremely versatile refractory material. Boasting superior acid resistance, low thermal expansion and minimal melting points, silicon carbide has many uses in modern engineering applications.
Additionally, ceramic can withstand extreme temperatures and stress without succumbing to corrosion or breakage, making it the ideal material for use in components for power electronics such as solar energy systems and electric vehicles. Furthermore, high voltage direct current transmission systems use ceramic as part of their transmission technology.
Wide bandgap allows electrons to freely pass between its valence and conduction bands, making it an excellent conductor of electricity. This ability enables it to handle higher voltage applications than monolithic silicon carbide and offers lower density with much greater fracture toughness compared to carbon fibers or oxide/oxide CMCs; helping reduce weight, costs and maintenance requirements while improving efficiency and performance. Chemical and temperature resistance make this material perfect for creating shot peening nozzles or components within cyclone separators.
Extremely Durable
Silicon carbide ranks second only to diamond in terms of Mohs hardness rating at 9, making it one of the hardest materials on Earth and virtually unbreakable. It can withstand high temperatures, corrosion resistance and has excellent abrasion resistance properties.
High strength steel allows it to withstand stress and heat, making it an ideal material for aerospace applications such as nozzle vanes and components within cyclone separators. Furthermore, its long lifespan helps lower operating and maintenance costs since replacement parts won’t need replacing as frequently.

High Resistance to Corrosion
Silicon carbide’s resistance to corrosion makes it an excellent material choice for aerospace engineering applications that face harsh environments, including turbine blades, nozzle vanes, and other components that must withstand high temperatures, pressures, and pressure without succumbing to erosion, corrosion, or thermal shock.
Silicon carbide’s chemical inertness allows it to thrive in environments that would normally damage other materials, making it an excellent choice for manufacturing parts that must endure sandblasting, cutting, and grinding operations.
Silicon carbide’s wide bandgap allows it to conduct electricity at higher voltage than traditional semiconductor materials, and by doping it with nitrogen, phosphorus or boron dopants engineers can further boost its performance – especially useful in creating power semiconductors where greater breakdown electric field strength is necessary.
High Young Modulus
Silicon Carbide exists in various polytypes, which differ based on how silicon and carbon atoms are arranged along its crystal axis. 3C-SiC (b-SiC) is the most prevalent polytype, as its isotropic properties make it the best candidate for manufacturing applications. When doped with boron, aluminium or nitrogen/phosphorus dopants it becomes p-type semiconductor material while nitrogen or phosphorus dopants convert it to an n-type semiconductor material while simultaneously increasing tensile strength/elastic modulus thus giving our CMC products their high Young Modulus properties.
