If a silicon nitride ceramic that is resistant to high temperatures and does not easily transfer heat is used to manufacture the heating surface of the engine component, not only the quality of the diesel engine can be improved, fuel is saved, but also thermal efficiency can be improved. The silicon nitride ceramic can be used as a gas turbine combustion chamber, a silicon nitride mechanical seal ring (silicon nitride ring), an electromagnetic pump pipe (silicon nitride tube) for conveying aluminum liquid, a valve, a permanent mold, a molten steel separation ring, and the like. Si3N4 ceramic is a covalent bond compound.
