Our Gas Pressure Sintering (GPS) process enables the production of low porosity.

The GPS process is a sequence of dewaxing, sintering at normal and high pressure, which enables a further densification and pore elimination.


Petroceramics has a well established experience in the GPS process and treatment of:

  • Sintered silicon nitride and sialon
  • Silicon carbide
  • Composite materials
