Silicon nitride is a man made compound which been synthesized through several different chemical reactions.
The parts are pressed and sintered by well developed methods to produce a ceramic with a unique set of outstanding properties.
The material is dark gray to black in colour and can be polished to a very smooth reflective surface.
High performance silicon nitride materials were originally developed for engine wear parts and military applications, however now Silicon Nitride finds its self being used in many different areas of industry, especially if it demands high reliability, severe mechanical, thermal and wear applications.
