A glow discharge starter having an hermetically sealed envelope of vitreous material, a seal located at one end thereof and containing an ionizable medium. A pair of electrical conductors extend through the seal and terminate in a spaced relationship to form a pair of electrodes within the envelope. At least one of the electrodes has a bimetallic element secured thereto. A coating comprising lanthanum, nickel and boron is disposed on a surface within the envelope. Preferably, the coating comprises from about 2 percent to about 4 percent boron. The coating is effective in improving the aging efficiency and the temperature stability of the glow discharge starter.
