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.
