POROUS

Sintered Porous Getters are Non-Evaporable Getter (NEG) alloys that are formed into porous structures, maximizing sorption performances at low temperature. Porous structures allow the gases to diffuse through the pores inside the getter mass, thus involving the inner part of the getter body in the sorption process. 

 

Highlights

  • Large getter mass and surface area in a small volume
  • High pumping speed at room T
  • Excellent mechanical properties
  • St-171 for high T activation
  • St-172 and St-175 for low T activation and in-situ pumping during baking process
  • St-175 can withstand air baking without dramatic loss of pumping performance

Final Applications

  • X-Ray Tubes
  • Microwave Power Tubes
  • Cooled and Uncooled IR sensors
  • Pressure Transducers
  • Mechanical and Laser Gyroscopes
