Sintered silicon carbide

Boostec® silicon carbide -SiC- for scientific instrumentation and industrial equipment

Mersen Boostec is specialized in the development of innovative products in sintered silicon carbide.

For some applications, the silicon carbide can receive a CVD (chemical vapor deposition) coating to give a completely non-porous high-purity SiC surface.


  • optical and scientific instrumentation (space or ground optics, stable structures, large scientific instruments, etc.)
  • chemical and pharma-chemical apparatus (continuous-flow reactors, heat exchangers, etc.)
  • mechanical applications (mechanical seals, bearings, thrust bearings, etc.)
  • mirrors for industrial laser systems
  • equipment for the semiconductor industry

Mersen Boostec is also involved in several cooperative projects, such as Sicsol, an innovative alternative energy project on concentrated solar power.

Prior to the actual ceramic manufacturing process, Mersen Boostec also advises and assists customers in the design of silicon carbide parts.


  • high purity composition, with no secondary phase
  • isotropic physical properties
  • low density
  • very high mechanical strength and rigidity (420 GPa)
  • insensitivity to mechanical fatigue
  • high thermal conductivity (180 W/m/K)
  • low expansion coefficient
  • exceptional resistance to corrosive and abrasive environments.

Mersen has held an 95.07% stake of Boostec since July 2015, and Boostec's main partner, Airbus Defence and Space (ex-Astrium), holds 4.93%.

Mersen Boostec's unique know-how in the design and manufacture of silicon carbide parts extends the Mersen group's range of equipment and solutions for extreme environments.
