Silicon nitride igniters are electrical components used to ignite fuel in various heating applications. They are made of a high-strength ceramic material known as silicon nitride (Si3N4). Silicon nitride igniters have several advantages over traditional metal igniters, including faster ignition times, longer service life, and higher temperature resistance.
