应用
Silicon(IV) nitride is used in the automobile industry as a material for engine parts such as diesel engines and glowplugs. It is used for rocker arm pads for lower wear in spark-ignition engines. Ceramics made from this show good shock resistance. Similarly bearings made from this find application in the main engines of NASA?’s space shuttle. It acts as an insulator and in the manufacture of integrated circuits.

展开

应用
Silicon nitride bearings are both full ceramic bearings and ceramic hybrid bearings with balls in ceramics and races in steel. Silicon nitride ceramics have good shock resistance compared to other ceramics. Silicon nitride is used for rocker arm pads for lower wear, turbocharger for lower inertia and less engine lag, and in exhaust gas control valves for increased acceleration.

备注
Store away from strong oxidizing agents. Keep container tightly closed. Store in cool, dry conditions in well sealed containers.
