Strength
Silicon carbide ceramic is an inorganic non-oxide material capable of maintaining its strength up to 1600degC. Due to its combination of high strength, low expansion rate, corrosion resistance and thermal conductivity properties it makes an excellent material choice for applications such as mechanical seals and pump parts as well as thermally conducting ceramic components like brake pads in consumer automobiles.
Silicon carbide stands out due to its combination of physical, mechanical, and chemical properties – these make it an integral component in modern technology and industrial applications. Its ability to withstand heat, chemical shocks, and absorb shock energy make this material indispensable in our society.
Silicon carbide boasts 5 to 10 times greater strength than 92% alumina material, boasting higher hardness than any engineering ceramic and providing greater abrasion resistance than any other engineering ceramic. Reaction bonded silicon carbide (RSIC/SISIC) offers excellent wear and corrosion resistance in extreme conditions such as high-temperature environments with strong abrasion or corrosion. Reaction-bonded silicon carbide ceramics can be tailored specifically to your equipment maintenance and replacement costs, with customizable shapes and sizes that fit your specific requirements.
Hardness
Silicon Carbide (SiC) is an exceptionally hard ceramic material, known to withstand both chemical and thermal shocks while showing exceptional mechanical strength under pressure. As such, SiC makes for an excellent material choice in applications requiring high performance materials that can withstand even challenging environments.
Sintered silicon carbide boasts superior ballistic capabilities as well as exceptional corrosion resistance and a Moh’s hardness of 9.5, higher than that of nitride-bonded silicon carbide used in applications like kiln lining.
Silicon carbide boasts the highest strength among all fine ceramics, maintaining its strength at temperatures as high as 1400degC without suffering damage. Due to this high temperature resistance, silicon carbide can be utilized in many industrial applications including mechanical seals and pump parts, semiconductor processing equipment, and general industrial machine parts.
Hexoloy SiC is a range of sintered silicon carbide products specifically developed for industrial applications. Saint-Gobain’s application engineers can assist you in finding the best Hexoloy SiC product to meet your application needs.
Wear Resistance
Silicon carbide is one of the hardest, lightest and strongest advanced ceramic materials available today. It is highly resistant to abrasion and erosion with second only to diamond and cubic boron nitride in terms of hardness. Silicon carbide also boasts excellent chemical resistance against acids while having an extremely low coefficient of thermal expansion that allows it to be made into shapes with close tolerances.
IPS Ceramics provides sintered and un-sintered silicon carbide to meet a range of high performance applications, with un-sintered versions used for applications requiring very high strength (such as wafer handling components).
Sintered versions boast superior mechanical properties and are used frequently in high temperature applications. Applications may include:
Corrosion Resistance
Corrosion resistance of ceramic materials refers to their ability to withstand contact with specific chemicals or environments, including acids and alkalis as well as corrosive solvents or gases. Corrosion resistance also takes into account a ceramic’s integrity when exposed to elevated temperatures if necessary.
Silicon carbide ceramic tiles are an ideal solution for applications requiring high chemical resistance or hardness, including mechanical seals, abrasion resistant pump components and semiconductor processing equipment. At temperatures reaching 1400degC they won’t deteriorate over time in strength or hardness while boasting excellent thermal conductivity and being electrically semi-conducive.
ALTRON’s sintered silicon carbide ceramics offer superior wear and corrosion resistance at an attractive cost, making them the ideal alternative to alumina bonded ceramics or tungsten carbide when your application requires advanced wear ceramics with exceptional toughness, temperature, and corrosion resistance. Available as plates, blocks and linings in various shapes including hexagonal tiles, cylindrical tiles, weldable tiles and more!
Thermal Conductivity
Silicon carbide ceramics boast exceptional properties in various fields such as mechanical, thermal and chemical performance – ideal for challenging industrial applications.
This special material maintains its strength at temperatures up to 1600degC and resists corrosion even in the presence of molten salts and acids, offering excellent fatigue resistance and chemical inertness properties.
Silicon carbide ceramic’s exceptional thermal conductivity stems from its complex crystal structure containing many tetrahedra – this makes silicon carbide ceramic more thermally efficient than many refractory materials and metals.
Silicon carbide ceramics boast one of the lightest, hardest, and strongest technical ceramics on the market, second only to diamond in terms of abrasion resistance and erosion/oxidation/grounding resistance. Furthermore, it features low coefficient of thermal expansion for increased stability as well as good dimensional stability making it suitable for use across a number of industrial sectors such as chemical processing and steel/machinery manufacturing industries.
