Abstract: A high pressure metal vapor lamp and a transparent polycrystalline alumina tube therefor have been disclosed. The average crystal grain size at ends of the tube is selectively made smaller than that of the middle portion of the tube so that the mechanical strength and the thermal shock resistance of the end portions are made higher than those in the middle portion. Accordingly, the tube hardly causes cracks by a thermal shock when the both ends of the tube are sealed and when the lamp using the tube is switched on and off. Whereas middle portion of the tube has an excellent transparency so that the lamp has a high luminance efficiency.
