Silicon carbide ranks third among the world’s hardest materials, trailing only diamond and cubic boron nitride in hardness. Though light, silicon carbide proves extremely durable.
Corrosion, abrasion and erosion can be easily managed while providing low frictional wear on mating metals. Furthermore, this material withstands high temperatures and pressures without deformation or failure.
High-temperature strength
Silicon carbide ceramics are highly resilient, offering resistance against both high temperatures and corrosion for extended service lives. Their tough exterior makes them suitable for demanding applications like slurry flashing, handling of HF acid solutions and rare earth processing.
Chemshun offers Reaction Bonded SiC ceramic lining solutions, including tiles, plates and blocks. Their tiles come in various forms such as retangular, triangle and hexagonal shapes to offer superior resistance against wear, impact wear and corrosion resistance.
Recent research has demonstrated that laser surface treatment of alumina and silicon carbide significantly enhances adhesive bond strength in quasi-static tests, due to increased concentrations of hydroxyl ions present. It is anticipated that this improvement in bonding will translate to superior ballistic performance for composite-backed armor systems.
High wear resistance
Silicon Carbide Ceramics stand out among advanced materials due to their superior abrasion resistance, making it one of the most durable options on the market. They can withstand impacts as powerful as those experienced with steel and cast iron materials, without suffering damage in return.
Material can withstand extreme temperatures, making it an excellent choice for aerospace applications such as building hypersonic aircraft and missile nose cones.
Reaction-sintered silicon carbide provides an ideal alternative to tungsten carbide for blast nozzles due to its low wear rate, enabling the nozzle to maintain its internal geometry while decreasing air compressor requirements and maintenance costs. Furthermore, reaction-sintered silicon carbide extends nozzle lifespan while simultaneously decreasing maintenance expenses.
Industrial applications that could use it include cyclones, tubes, chutes, hoppers and pipes. Furthermore, it can also be transformed into structural parts such as beams, rollers, cooling air pipe systems with temperature measurement pipes for burner nozzles as well as corrosion-resistant and sealing parts.
Low density
Silicon Carbide can be machined easily in its green, or biscuit state. Unfortunately, sintering processes that fully densify it cause its body to shrink 20% and make maintaining tight tolerances difficult.
SiC’s low density allows it to withstand the impact of high-velocity projectiles without compromising its strength, making it ideal for ballistic performance testing at STANAG 4569 Level IV. Alumina and SiC composite panels were tested under these conditions, with sintered silicon carbide panels showing less damage during testing.
IPS Ceramics provides sintered silicon carbide tiles and linings that provide corrosion- and abrasion-resistance while remaining frictionless for use in production systems, including cyclones, tubes, chutes, hoppers and production liners. Our material offers excellent corrosion and abrasion resistance with an extremely low coefficient of friction – an unrivalled combination of properties!
High corrosion resistance
Silicon carbide ceramics exhibit numerous desirable physical-chemical properties that have made them popular choices for high performance applications, including hardness, density and corrosion resistance. Furthermore, their thermal stability and limited expansion properties make them suitable for advanced aerospace uses like hypersonic aircraft and missile nose cones.
Reaction-sintered Silicon Carbide Ceramic liners are commonly employed across industries to protect equipment against strong impacts and wear-and-tear. Such applications include coal industry, metallurgy & power industry and chemical industries, among others. Furthermore, they may be utilized mechanical sealing applications, surface sandblast treatment treatment as well as reflector applications.
High abrasion resistance
Silicon carbide (SiC) ceramics can be found in many chemically resistant applications, from industrial wear resistance to high temperature resistance. Their characteristics make them extremely hard and lightweight with superior wear resistance in harsh environments – including high temperatures. Furthermore, SiC ceramics can easily be formed into complex shapes for large or small projects alike.
Ballistic tests were performed on composite-backed alumina and SiC panels to assess their ballistic performance. After multiple bullet impacts were received by these panels, qualitative analysis of damage sustained and failure location of adhesive bond was made for evaluation purposes.
Reaction-sintered silicon carbide (RSiC) is an ideal material choice for demanding abrasion applications, boasting 7-10 times greater abrasion resistance than alumina. Furthermore, its excellent impact strength makes RSiC the ideal material to line pumps, valves and other critical components.
