この発明はハロゲン電球、水銀灯に適する管球ウェルズ
に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] This invention relates to a bulb well suitable for halogen bulbs and mercury lamps.
ステム、パルプに石英ガラスを使用するハロゲン電球、
水銀灯は石英ガラスの軟化点が高いためステムとクエル

ズ材料としては耐熱強度を要する点からモリブデン線が
広く使用されている。Halogen light bulbs that use quartz glass for their stems and pulp;
Since the softening point of the quartz glass in mercury lamps is high, the sealing of the stem and quells is resistant to temperatures of 1000 to 1200°C in ordinary light bulbs.
It is carried out at a high temperature of 600-170°C. Molybdenum wire is widely used as such a well material because it requires heat-resistant strength.
現在、このような場所に使用するモリブデン線は添加物

。Here, AI for molybdenum, 84. By the addition of , micro dope holes arranged in the processing direction are generated by the heat treatment during high temperature sealing of Actariet made of cold worked molybdenum alloy, and secondary recrystallized grains are formed due to the effect of these micro dope holes. It is necessary to increase the resistance, and when it is less than 0.005% by weight, the secondary recrystallization temperature is low and the resistance after secondary recrystallization is small and the properties are insufficient. If it exceeds 0.75%, the sinterability of the molybdenum green compact and the workability such as wire drawing of the secondary sintered compact will be greatly reduced, making this composition range preferable.
