Specifications
Silicon Nitride Ceramic/Si3N4 Cermaic Shaft For Transmission/INNOVACERA
Material Description
Silicon nitride color is dark gray to black and can be polished to a very smooth reflective surface.
High performance silicon nitride materials were developed for automotive engine wear-resistant
parts, such as valves and cam followers and proven effective. The very high quality bodies developed
for using in many severe mechanical, thermal and wear applications.
Key Silicon Nitride (Si3N4) Characteristics:
? Good thermal shock resistance
? Creep resistance
? Low density
? High fracture toughness
? High hardness and wear resistance
? Electrical resistivity
