(inorganic chemistry)
Si3N4 A white, water-insoluble powder, resistant to thermal shock and to chemical reagents; used as a catalyst support and for stator blades of high-temperature gas turbines.

silicon nitride

(Si3N4) A silicon compound capable of holding a static electric charge and used as a gate element on some MOS transistors.

Geographically, the global silicon nitride market is segmented into North America, Asia Pacific, Europe, Middle East & Africa and South America.
Through this approach, a thermometer that could measure fast and small temperature changes were successfully produced, with the measurements being performed through the nano-thin silicon nitride membrane.
Almost every Formula 1 engineering team uses ball and roller bearings with silicon nitride rolling elements, thanks to their light weight (the ceramic material has only 40 percent of the density of steel), low friction properties and resistance to high temperatures and vibration.
For example, silicon nitride is a large bandgap (~5 eV) deposited material that is compatible with CMOS fabrication technology.

Black silicon technology can eliminate the plasma-enhanced chemical vapour deposition (PECVD) of silicon nitride currently in solar cell production lines.
At present, hydrogen containing silicon nitride ([SiN.sub.x]:H) thin film deposited by plasma enhanced chemical vapour deposition (PECVD) is widely used as ARC and passivation layer for crystalline silicon solar cells [5, 6].
