product introduction:
Alumina ceramic igniter is a kind of ceramic product used in electric burner igniter. Electric burners often use igniter to ignite. The igniter generally emits electric sparks through the igniter electrode, and the outer surface of the igniter electrode requires an insulated, high-temperature resistant and explosion-proof protective sleeve. Usually, ceramic igniter is used for protection.
