Silicon nitride(Si3N4)exceeds many other ceramic materials in thermal shock-resistance.It does not deteriorate at high temperatures;therefore,it is ideal for use in components for automotive engines and gas turbines-including turbocharger rotors,glow plugs for diesel engines,and hot plugs.Further applications of this material are anticipated in a wide range of fields.
