(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.

Also, we made the reference measurements, which gave us corrected values of the Scholte wave propagation at the water and silicon nitride interface (1380 m/s versus 1410 m/s) and at the isopropanol and silicon nitride interface (1125 m/s versus 1170 m/s).
