Sintered Silicon Carbide

Blasch ULTRON Sintered Silicon Carbide (SSiC) is produced using very fine silicon carbide powder containing sintering additives. It is processed using forming methods typical for other ceramics and sintered at 2,200°C in an inert gas atmosphere.

ULTRON Sintered Silicon Carbide is distinguished by exceptionally high strength that stays nearly constant up to very high temperatures (approximately 1,600°C) with no degradation over time.


  • The material displays an extremely high corrosion resistance in acidic and basic media and is maintained up to very high temperatures
  • Properties are outstanding among high-temperature ceramics, complemented by high thermal shock resistance, high thermal conductivity, high resistance to wear, and hardness close to that of a diamond
  • Ideal for extremely demanding applications, for example, slip ring seals in chemical pumps, bearing bushes, high-temperature burner nozzles, or as kiln furniture for very high application temperatures
