Product Description

Silicon Nitride Si3N4 Ceramic Rods Shafts

Silicon nitrides (Si3N4) feature an excellent combination of material properties. They are nearly as light as silicon carbide (SiC), but their microstructure gives them excellent thermal shock resistance and their high fracture toughness makes them resistant to impacts and shocks.

Key Properties of Silicon Nitride 
*High strength over a wide temperature range
*High fracture toughness
*High hardness
*Outstanding wear resistance, both impingement and frictional modes
*Good thermal shock resistance
*Good chemical resistance

Different Types of Silicon Nitride Ceramics
(1)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.

(2)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 Silicon Nitride applications
1.Bearing balls and rollers
2.Cutting tools
3.Valves, turbocharger rotors for engines
4.Turbine blades
5.Glow plugs
6.Molten metal handling
7.Thermocouple sheaths
8.Welding jigs and fixtures
9.Welding nozzles
