Abstract
PURPOSE: To eliminate scattering of electron emitting material from an electrode at sealing time by thermally treating the electrode in vacuum at the same or higher temperature as or than heat treating temperature at sealing time of the electrode before sealing step.
CONSTITUTION: After electron emitting materials is coated on the electrode coil of an electrode 3, it is calcined at 1800°C in rare gas atmosphere, and the electrode 3 is then raised at a rate of 100°C./min. to 1500°C. in vacuum atmosphere, and maintained at the same temperature for 10 minutes, then cooled to the room temperature for its heat treatment. This discharge lamp is produced by sealing the electrode thus treated in a schedule of sealing at 1400°C. for 10 minutes, and then treating a lamp fabrication step.
