Silicon Nitride has the most versatile combination of mechanical, thermal, and electrical properties of any technical  ceramic material. It is a high performance technical ceramic that is extremely hard and has exceptional thermal  shock and impact resistance. It surpasses most metals high temperature capabilities and has a superior combination  of creep and oxidation resistance and high strength. Additionally, its low thermal conductivity and high wear  resistance make it an excellent material that can withstand the toughest of conditions in the most demanding  industrial applications. Silicon Nitride is an excellent choice when high-temperature and high-load abilities are  needed.
