Silicon carbide in mechanical seal assemblies yields numerous benefits, including enhanced performance, extended seal lifespan, reduced maintenance expenses, and decreased operating costs for rotating equipment such as turbines, compressors, and centrifugal pumps. These seals help minimize the risk of leakage and catastrophic failure, ensuring environmental protection against fugitive emissions. Additionally, Silicon carbide seals contribute to lower energy consumption by reducing friction during start-up and shutdown procedures, as well as minimizing wear and erosion during operation. Silicon carbide seals exhibit exceptional durability, thereby increasing the mean time between failures and resulting in improved productivity and reduced total cost of ownership for processing equipment.

Product detail

silicon carbide mechanical seal

Mechanical seals are required to function effectively in demanding operating conditions, including high speeds, temperatures, and pressures, all while maintaining resistance to corrosion and wear. Technical ceramics offer the ideal combination of toughness, stiffness, flexural strength, hardness, and corrosion resistance for mechanical seals. They are particularly well-suited for dry gas seal assemblies, which necessitate minimal deflection at high speeds and low thermal expansion at elevated temperatures.

Mascera produced silicon carbide ceramics in two forms, sintered silicon carbide (SSiC) and reaction bonded silicon carbide (SiSiC). 


Sintered silicon carbide ceramic is made of high-purity and nano-grade raw powders and sintered at a high temperature of 2100℃-2200℃, the sintering process will densify the green body and cause shrinkage approximately 20%; reaction boned silicon carbide uses micron-sized silicon carbide powder, the sintering temperature is 1450℃-1700℃, there is no shape shrinkage during sintering. The higher sintering temperature makes sintered silicon carbide having better performance, such as higher density, higher strength, better resistance to oxidation and corrosion; for applicatons which don't have so high properties requirement, reaction bonded silicon carbide is more cost effective.


Main properties of silicon carbide ceramic

  • High strength in high temperature

  • High-temperature oxidation resistance

  • Excellent wear resistance

  • Low thermal expansion coefficient

  • High thermal conductivity

  • Excellent thermal shock resistance

  • High hardness

  • Light weight because of low density

  • Good corrosion resistance
