Silicon Nitride has the best combination of mechanical, thermal and electrical properties of any technical ceramic material. It is a high performance technical ceramic with high strength, toughness and hardness, and is extremely resistant to thermal shock and impact. It is also an electrically insulating ceramic material. Typically, it is used in applications where high load-bearing capacity, thermal stability and wear resistance are required.

Sialon (Silicon Aluminium Oxynitride) is a silicon nitride ceramic with a small percentage of aluminum oxide added. It is a nonporous engineering material with superior thermal and mechanical properties compared with silicon nitride. Sialon is an ideal material for applications where strength at high temperature, thermal shock resistance, and corrosion resistance are needed.
