Silicon Carbide Plate

Silicon carbide plate is an extremely durable refractory ceramic material with outstanding mechanical, thermal and chemical properties that makes it suitable for numerous industrial applications including armor and ballistic protection, cutting tools and wear-resistant components.

Produced by grinding silica sand and mixing it with carbon powder in the presence of non-oxide sintering aids to form a pasty mixture, then compacted by cold isostatic pressing or extrusion into various shapes.


Silicon carbide is one of the hardest materials on Earth. A covalent compound of carbon and silicon, it offers corrosion-resistance and extreme hardness as well as low thermal expansion and rigidity – qualities which have led to widespread uses across numerous applications.

Moissanite occurs naturally as the gemstone moissanite, but has been mass produced since 1893 as powder and crystals to serve as an abrasive material. Through sintering it can also be bound together to form hard ceramics used in body armor systems.

Nickel silicon carbide applied via electroless process provides consistency that allows sharp corners and recesses to retain their sharp edges, without coating build-up clogging blind holes or thru-holes, to ensure proper operation of equipment with reduced maintenance costs by limiting downtime. This allows full coverage coating of blind holes or thru-holes without blocking blind holes with coating buildup; this guarantees proper operation of equipment as well as reduced downtime, thus minimizing maintenance costs by limiting downtime.

Corrosion resistance

Silicon carbide is an extremely durable material, resistant to corrosion in various environments. It features high thermal stability and resistance to most chemicals and gases; furthermore it boasts low coefficient of thermal expansion as well as strong mechanical properties.

Silicon carbide ceramics are easily manufactured, making them an excellent choice for industrial applications. Parts can be created through extrusion and cold isostatic pressing processes to form tubes, blocks and plates for use across many industries.

Reaction bonded silicon carbide (RB SiC) is an outstanding refractory ceramic used in various applications, from furnace linings and kiln components to molten salt slag smelters. It boasts excellent corrosion resistance due to a protective oxide layer on its surface that blocks oxygen’s direct reaction with silicon metal and prevents further oxidation of substrate surfaces, thus offering high levels of protection even against harsh environments like molten salts and coal ash slags.

Thermal conductivity

Silicon Carbide (SiC) is a hard chemical compound composed of carbon and silicon that occurs naturally as the gemstone moissanite; however, since 1893 mass-production for high performance ceramic applications such as bulletproof vest plates has begun. SiC exhibits excellent corrosion resistance with very low thermal expansion coefficient. Furthermore, it can tolerate extreme temperatures.

Liquid-phase sintered polycrystalline 3C-SiC with Y2O3-Sc2O3 additives has an intrinsic thermal conductivity of 261.5 W/m-K; significantly lower than expected by simple theory due to strong boron defect-phonon scattering1,2.

Stanford Advanced Materials (SAM) offers an expansive selection of SiC plate for various uses. Available in different sizes and thicknesses, this material can be custom fabricated to meet specific specifications and can even be custom fabricated into shapes to meet exact needs. SiC is especially well suited to applications involving erosion such as those found in shot blast nozzles and cyclone components due to its highly resistant crystalline structure that prevents acid attacks while still offering good wear performance under hot environments.

Chemical resistance

Silicon carbide is an inert material with excellent chemical and thermal conductivity properties, making it suitable for use in harsh environments including corrosive ones. Furthermore, this hard material boasts exceptional durability and resistance against abrasion.

Moissanite can be found naturally as the rare gem moissanite, but since 1893 mass production has made this material widely used as an abrasive and for its strong ceramic properties. As part of such mixes it’s often mixed into bulletproof vests, shields and barricades used by law enforcement officers and security teams for bulletproof protection.

Chemically, SiC has excellent corrosion resistance in molten salt environments due to the formation of an oxide barrier that protects it from directly reacting with attacking species. This effect is achieved thanks to its structure comprised of four hexagonal layers of silicon atoms and carbon atoms which result in parabolic reaction kinetics when oxygen attacks it; additionally, carbon substitution helps lower surface concentration of free oxygen concentration.
