Gas pressure sintered silicon nitride (GPSSN) is a sintering processing at high temperature after isostatic pressing of silicon nitride powder with other additives. The nitrogen pressure (<20mpa) during sintering could restrain the dissociation of si3n4 and get the full sintering at high temperature, which make the silicon nitride products to highest density and lowest porosity.

Product Advantages

  • 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
  • Good corrosion resistance

 
Common size
We can also prodcue other sizes according to your drawing.
