Sintered Silicon Nitride Ceramics
SSN is a high purity grade of silicon nitride having a density of approximately 70-80% of theoretical that can be produced in a cost effective manner such as dry pressing, and isostatic pressing, to complex net shapes.  SSN has excellent thermal shock resistance and outstanding compatibility with non-ferrous molten metals.  This lower cost alternative to the fully dense silicon nitride grades can be manufactured to close tolerance without the need for expensive diamond grinding.

Hot Pressed Silicon Nitride Ceramics
HPSN can be formulated into a variety of compositions having minimal densification aids.  HPSN compositions offer the highest strength of silicon nitrides

Typical applications:

• Semiconductor handling parts
• Wafer processing components
• Bearing balls and rollers
• Nozzles
