Silicon carbide (SiC) ceramics are an outstanding material suitable for demanding industrial applications, featuring superior temperature resistance, chemical stability, and mechanical strength properties that make it suitable for modern manufacturing environments.
With energy taxes or sustainability targets placing pressure on tile manufacturers to improve energy efficiency and lower CO2 emissions, tile manufacturers must find ways to maximize energy savings while simultaneously cutting CO2. At Saint-Gobain PCR we offer an extensive range of SiC products designed specifically to help tile makers reach these goals.
High Temperature Resistance
Refractory ceramics such as silicon carbide have an operating temperature of 2000degC and offer exceptional chemical stability, making them the go-to material in numerous industrial applications. Renowned for its mechanical strength, hardness, elasticity modulus wear resistance and thermal conductivity properties this material stands out as one to consider for industrial applications.
Saint-Gobain offers an impressive range of Hexoloy(r) silicon carbide ceramics designed for critical applications, from reaction bonded and sintered products through sintered and recrystallized grades for use in tunnel kilns, shuttle and roller kilns, nuclear power cladding materials and chemical processing equipment. Each grade boasts exceptional thermomechanical properties across an extensive temperature range for exceptional thermomechanical performance over its lifespan – ideal for tunnel kilns, shuttle and roller kilns as well as nuclear power cladding materials or chemical processing equipment applications.
When selecting the ideal refractory material for your application, first review industry compliance standards and specifications. For example, medical products require ISO 13485 certification while aerospace components should adhere to AS9100 specifications while chemical processing equipment needs NACE MR0175 specifications. Next, assess density (>3.10 g/cm3) purity thermal shock resistance fracture toughness as key attributes when choosing materials suitable for your operation.
Thermal Shock Resistance
Silicon carbide (SiC) is a strong, heat-resistant fine ceramic used in various industries due to its exceptional mechanical properties. From hardened tool steels and wear-resisting linings to wear-resistant components and efficient machine components – silicon carbide offers many applications across industry sectors.
Due to its low coefficient of thermal expansion and high strength, PEEK is widely used in the production of chemical resistant valves, pumps and seal rings as well as mechanical seals which must withstand heavy loads or impacts.
SiC ceramic boasts superior chemical resistance and mechanical hardness compared to its Alumina counterpart, as well as exceptional high-temperature strength; it can withstand temperatures up to 1,900degC without cracking, making it suitable for many industrial processes like mining, natural stone processing and food production.
Chemical Resistance
Silicon carbide excels at resisting corrosion in complex chemical environments, making it an invaluable material choice in industrial settings that utilize corrosive, aggressive or toxic chemicals in their production processes. Its resistance against such environments makes silicon carbide especially suitable for applications involving harsh industrial conditions that would compromise lesser materials. This quality makes Silicon Carbide ideal for use as part of manufacturing processes using aggressive substances – whether that means using aggressive abrasives like diamond powder to cut steel sheets for example – or toxic substances in manufacturing processes like producing metal products containing silicon.
SIC ceramic sheets can withstand temperatures up to 1600 degC without compromising their structural integrity, and are extremely resistant to granular abrasion and erosion, meaning that they can withstand mechanical loads and impacts while remaining resilient against these threats.
Silicon carbide ceramics boast excellent thermal conductivity for effective heat dissipation, while their low coefficient of expansion ensures minimal changes to dimensions due to temperature variations. Due to these properties, silicon carbide plays an integral role in modern technology and industrial applications: aerospace, automotive, metallurgical, energy, information electronics as well as other cutting-edge industries rely heavily on this versatile refractory ceramic. With hardness, thermal stability and chemical inertness characteristics making SIC one of the most versatile refractory ceramics on offer today.
Wear Resistance
Silicon carbide ceramics are the go-to choice for critical applications that demand high abrasion resistance, chemical stability and thermal shock resistance. Used across industries from abrasives to aerospace components due to their impressive physical-chemical properties, silicon carbide ceramics have quickly become one of the premier choices available today.
Solid-phase sintered silicon carbide offers remarkable corrosion and abrasion resistance, along with exceptional mechanical stress resistance, making it an ideal material for pump parts, valve seals and other mechanical systems that experience constant friction or impact. Furthermore, its superior sliding friction against various mating materials offers distinct advantages over ceramics or metals.
