Silicon Nitride (Si3N4) Description:

Silicon nitride is a man made compound synthesized  through several different chemical reaction

methods. Parts are pressed and sintered by well developed methods to produce a ceramic.

The material 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
