Silicon carbide ceramic is a non-oxide ceramic material featuring high bending strength and exceptional chemical and oxidation resistance, making it suitable for various production methods such as hot pressing, HIP sintering or reaction-bonded sintering.
Ballistic tests showed that SiC of various thicknesses was effective against 7.62x54mmR armor-piercing projectiles under weak constraint conditions due to self-constraint on damaged ceramic parts within ceramic materials.
High-strength
Silicon carbide is an advanced refractory ceramic that offers high strength, wear resistance, corrosion resistance and thermal stability. With a low coefficient of expansion at high temperatures and no shrinkage during high-temperature use such as metal smelting furnaces or petrochemical production processes, silicon carbide makes an excellent material choice for cut-off wheels, grinding wheels as well as automotive components and refractory materials.
Silicon Carbide Ceramics offer comparable ballistic performance to that of Alumina and Titanium materials, yet are capable of withstanding higher velocities. Unfortunately, its inherent weakness is its low toughness: molecular structures may fracture under impact. Therefore, such ceramics should only ever be used once.
NASA’s Glenn Research Center researchers have created new technologies combining non-oxide SiC fibers and matrices in order to increase silicon carbide’s performance, creating ceramic composites designed to withstand harsh structural and environmental conditions up to 2700degC for extended periods. These ceramic composites can be found in high temperature applications like high-temperature molten metal and coal slag linings in gas turbine engines as well as hot components found within automotive, mechanical and oil/petrochemical sectors – making these ceramic composites highly versatile.
Lightweight
Silicon Carbide ceramic plates are one of the lightest and hardest technical ceramic materials, with excellent acid resistance, low thermal expansion and minimal wear resistance properties that make it suitable for applications involving erosion resistance and wear resistance. Their properties also make Silicon Carbide plates suitable for production of spray nozzles, shot blast nozzles and cyclone components.
Silicon carbide is non-toxic and inert, making it safe to use across a range of environments – particularly those exposed to chemicals regularly. Furthermore, silicon carbide offers exceptional corrosion resistance as it’s less prone to damage compared to other materials.
Silicon carbide is an ideal material for body armor due to its versatile capabilities. It can withstand threats such as bullets, armor-piercing rounds and high velocity fragments while being resistant to abrasion and chemical degradation. Furthermore, silicon carbide plates are lighter compared to other armor materials which allows for greater mobility and comfort for its wearer.
Stanford Advanced Materials (SAM) offers a selection of SiC ceramic plates designed to meet the demanding needs of US military forces. Constructed using a blend of Silicon Carbide and Boron Carbide for optimal strength-to-weight ratio, these ceramics have been tested according to National Institute of Justice standards to withstand ballistic impacts as well as projectile threats such as bullets or bombs.
High-temperature resistance
Silicon carbide is widely known for its remarkable heat resistance, making it suitable for numerous industrial and commercial applications. Its high melting point means that it can withstand high temperatures without weakening, while maintaining low thermal expansion rates at higher temperatures and resisting chemical attack – qualities which make silicon carbide an ideal material choice in many situations.
Elastomeric materials offer excellent abrasive resistance, making them suitable for sandblasting applications and their light weight make them an efficient alternative to steel plate. Furthermore, their resistance to corrosion makes them suitable for high-tech military equipment applications.
Although rubber has numerous advantages, one drawback stands out: Its low toughness. This could impede its ability to protect against bullets. Furthermore, rubber may crack or shatter upon impact reducing protection capabilities significantly and possibly making multiple shots impossible.
Chemshun Reaction Bonded Silicon Carbide Ceramic (SISIC) plates can be created through various fabrication processes, including hot press, HIP and reaction-bonded sintering. The latter involves heating green bodies to high temperatures before producing dense, wear-resistant and corrosion resistant plates suitable for numerous industrial and commercial uses such as ceramic high temperature kilns, steel mill quenching furnaces, mine material classification cyclones, large boiler and power plant desulfurization and dust removal equipment, coal slag pneumatic conveying equipment and mechanical sealing equipments.
Chemical resistance
Silicon carbide is one of the hardest, strongest, and lightest technical ceramic materials on the market. Able to withstand high temperatures without cracking under pressure, its corrosion-resistance makes it ideal for industrial processes involving harsh chemicals; furthermore it boasts excellent oxidation resistance with minimal thermal expansion – qualities which make it an excellent material choice for spray nozzles used in cyclones or shot blast nozzles used with them.
IPS Ceramics provides several grades of silicon carbide plates designed to meet the diverse needs of different industries. Our plates can be cut to your precise dimensions, making them suitable for many different applications. In addition, these non-toxic and inert materials are great options for use across a range of environments.
Silicon carbide plates have the strength to withstand heavy loads, making them an excellent choice for load-bearing applications in temperatures ranging from 1700oC to 1800oC. In addition, their pressure resistance and creep resistance make them less prone to damage than other materials; making it perfect for applications involving vibration or shock.
Silicon Carbide Plate with Lateral Confinement improves ballistic performance further by limiting fragments from ceramic fracture and increasing dwell time by restricting their movement within its confines, thus minimizing damage and lengthening dwell time.
