Silicon Nitride material is one of the hardest materials in the world with extrusion molding process and hot isostatic pressing sintering adopted during the production. Its high strength, wear resistance, temperature resistance, corrosion resistance, acid resistance and alkali resistance can well ensure the purity of materials.

Si3n4 Silicon Nitride Tube , Silicon Nitride Thermocouple Protection Tubes

Features:

  • Moulding: Cold isostatic pressing(CIP)
  • Sintering: GPSN/RSSN
  • High strength and good compactness
  • Low thermal expansion coefficient
  • Excellent thermal shock resistance
  • No wetting by molten aluminum and non-ferrous metal
  • Thermocouple's long-time stability and service life will be up to outside protection tube.
  • Thermocouple shielded by silicon nitride thermocouple sheath will quickly react to temperature due to its good thermal conductivity and thinner wall thickness.
  • Silicon nitride thermocouple protection tube is for continuous temperature measurement and protect thermocouple without erosion.
