SiNLAST® – Silicon Nitride Si3N4

JJISCO's SiNLAST silicon nitride is a gas pressure sintered Si3N4 material matrix. Made from a uniform fine grain structure, it is a high performance technical ceramic that is extremely hard and has exceptional thermal shock and impact resistance. Its high temperature capabilities are much greater than most metals.  SiNLAST exhibits a superior combination of creep and oxidation resistance while maintaining high strength. Additionally, its low thermal conductivity and high wear resistance make it an excellent material that can withstand the toughest of conditions in the most demanding industrial applications.

  • Superior performance in dynamic and high thermal shock applications
  • World-class technology for electrical insulation
  • Superior hot hardness and high strength at high temperatures with low thermal expansion
  • Excellent abrasion and wear resistance
  • Extreme corrosion resistance / chemical stability versus other hard materials

SiNLAST performs where both standard and complex geometries are involved:

Bearings  •  Bushings  •  Nozzles  •  Wear Pads  •  Wear Rings  •  Rollers  • Thrust Washers
Electrical Insulators  • Photovoltaic Parts   • Thermocouple Protection Tubes   • Welding Parts

Silicon Nitride is workhorse for corrosion and wear resistance where chemical attack and thermal shock exists.  Below are typical property values:
