    • Cermet for a lamp containing at least a substance larger in linear thermal expansion coefficient than a transparent ceramics forming the discharge vessel (10) of a ceramic discharge lamp and a substance smaller in linear thermal expansion coefficient than the transparent ceramics. The ceramic discharge lamp provided with a ceramic discharge vessel having an arc tube (11) housing a pair of electrodes (21) therein and a side tube (12), wherein a sealing member (24) in which the base end of an electrode rod (22) having an electrode (21) at the tip end thereof is embedded, is frit deposited on the side tube (12) to thereby form a sealing structure, the sealing member (24) comprising the above cermet for a lamp.
    • 用于至少含有比形成陶瓷放电灯的放电容器(10)的透明陶瓷的线性热膨胀系数大的物质的灯的金属陶瓷和比透明陶瓷更小的线性热膨胀系数的物质。 陶瓷放电灯设置有陶瓷放电容器,该陶瓷放电容器具有容纳一对电极(21)的电弧管(11)和侧管(12),其中密封构件(24),其中电极杆 在其末端具有电极(21)的电极(22)被嵌入,在侧管(12)上玻璃料堆积,从而形成密封结构,密封构件(24)包括上述用于灯的金属陶瓷。
