Silicon carbide (SiC) is an exceptionally hard and durable ceramic. Due to its excellent thermal conductivity and low thermal expansion coefficient, SiC makes an excellent refractory material; furthermore it resists abrasion very effectively.
Moissanite occurs naturally only in very limited quantities as the gem moissanite and is mass produced via Lely process as powder and crystal to serve as abrasives.
Reaction Bonded Silicon Carbide Sleeves
Reaction bonded silicon carbide (RB SiC) is an economical material solution that boasts exceptional wear resistance and thermal stability, making it suitable for industrial uses like pumps, mechanical seals, flow control chokes, bearings, and other high-temperature components. Produced in various shapes and sizes this durable ceramic can often be found used as the core material in pumps, mechanical seals, flow control chokes, bearings or any high temperature component.
Reaction bonded ceramics are formed through infiltrating molten silicon into a carbon graphite preform, producing ceramic material with strong chemical resistance even in aggressive environments.
For applications that demand enhanced lubrication properties, RB SiC can be combined with free graphite particles to form graphite-loaded silicon carbide (GC SiC). This option is particularly suited for instances in which free silicon metal reduces chemical resistance – unlike tungsten carbide which needs cobalt or nickel binding for chemical inertness, GC SiC offers corrosion-resistance capabilities on its own – making it the perfect material choice for critical environments.
Reaction Bonded Silicon Carbide Tiles
Reaction Bonded Silicon Carbide (RBSC) is an exceptionally tough ceramic form of silicon carbide used widely in industrial furnaces, kilns, and semiconductor manufacturing equipment.
RBSCs are produced by infiltrating porous silicon carbide preforms with liquid silicon, infiltrating their ceramic body through capillary action to form additional SiC and bond existing a-SiC particles. Once all the silicon has been added, the ceramic part is sintered at temperatures close to its melting point in order to provide greater consistency in strength compared to traditional methods and produce an a-SiC structure with no shrinkage issues.
RBSC is impervious to acid corrosion, making it an ideal material choice for components exposed to moderately caustic or acidic fluids. Our premium material, Calsic RB, is often utilized in industrial furnaces and kiln furniture applications; in addition, its good wear resistance provides thermal shock resistance.
Silicon Carbide Sheets
IPS Ceramics provides large reaction-bonded silicon carbide (RBSiC or SiSiC) sheets in standard sizes and thicknesses to meet your application needs. RBSiC ceramics feature exceptional mechanical strength, abrasion resistance and temperature tolerance – characteristics which will help ensure their success in your environment.
Hard and durable ceramic material such as zirconia is often chosen for applications requiring resistance against abrasion and wear in industrial ceramics and wear-resistant tiles within the chemical industry. Its resilience allows it to withstand heavy loads and pressures present in demanding environments like aerospace and automotive sectors.
Silicon carbide’s exceptional hardness stems from its crystal structure. Its tight tetrahedral arrangements of silicon and carbon atoms form strong covalent bonds in its crystal lattice that impart its extraordinary hardness.
Silicon carbide is ideal for applications involving rapid temperature changes due to its extremely low coefficient of thermal expansion and high thermal conductivity. Furthermore, silicon carbide’s excellent load-bearing capacity at elevated temperatures makes it particularly valuable in environments involving mechanical stress loads – these qualities make silicon carbide components suitable for furnace components, kiln furniture and sealing surfaces like seals.
Silicon Carbide Strips
Silicon carbide is an impressive material capable of fulfilling an array of demanding tasks. Due to its tough, durable crystalline structure, silicon carbide can often be found in abrasive tools such as sandpapers and grinding wheels; additionally it can also be found as wear-resistant components in refractories or used as wear-resistent linings and wear-resistant components in wear resistant components and also serves as a semiconductor substrate in light emitting diodes (LED).
Silicon Carbide, with its impressive thermal, electrical and mechanical properties has become an indispensable material in critical applications today. From satellites and missile control systems to aerospace applications such as satellite communication systems and missile launch pads – silicon carbide has proven its worth time after time when subjected to harsh environments that involve high voltages and temperatures.
