Si3N4 is a technical ceramic material with high performance
that is extremely hard and has high thermal shock and impact
resistance at both room and high temperatures. The material is
an electrical insulator and is resistant to attack by many molten
metals. It can be polished to a very smooth reflective surface.
Silicon nitride materials have been developed for automotive
engine wear parts, such as valves and cam followers, and
bearing.

Characteristics
- High mechanical strength, such as fracture toughness,
hardness, and wear resistance, over a wide
temperature range - Low Coefficient of Friction, contact Fatigue Resistant
- Low thermal conductivity and excellent thermal shock
resistance - Good chemical corrosion resistance to acids, alkalis,
inorganic and organic salts, and seawater. - High temperature ceramic bearing that can be used to
1000°C, and self lubrication, no grease or oil required.
High reliability at high speeds and loads - Lightweight, non-magnetic and electrical insulation
