What are the advantages of Silicon Nitride?

Compared with other technical ceramics, the low thermal expansion coefficient of Silicon Nitride provides good thermal shock resistance. It is extremely hard, fracture-tough, surpasses the high temperature capabilities of most metals, and also has a superior oxidation resistance. As a consequence, silicon nitride can withstand the toughest conditions in the most demanding high-temperature and high-load applications.

What is the formula for Silicon Nitride?

The formula for silicon nitride is Si3N4.
