Silicon(IV) nitride, 99.3% (metals basis), typically 90% beta-phase, Thermo Scientific Chemicals

Description

Silicon(IV) nitride is used in 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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
