For example, it is used in gas turbines to make combustion chambers and other high-temperature parts. Silicon nitride supports high operating temperatures and increases the energy efficiency of aircraft engines while reducing operating steps and fuel consumption. High thermal conductivity and the ability to withstand thermal shocks offer proficient heat transfer increasing the efficiency of heat exchangers. 

Moreover, the higher thermal stability of silicon nitride makes it suitable for metallurgical operations such as smelting and casting materials and high-temperature electronic applications. Its mechanical strength and durability under high-temperature conditions and rapid heat dissipation properties make it the preferred material for cutting tools with long life and high productivity.
