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.
Packaging Details:

• We general have two types for safe package: carton and pallet.
• If there's special demands, we will respect your suggestion.

Delivery Detail:

• General within 20 working days, it depends on the quantity.
