    • The seal between the insulator and the center electrode is to be improved in a spark plug for an internal combustion engine comprising a shell (12), an insulator (16) located in the shell and composed of a sintered ceramic material, as well as a center electrode (18) and a terminal stud (22) that have an electrically conductive connection with each other and are located in the insulator. For this purpose, it is provided that a cermet (28) abuts the center electrode, the ceramic phase of which is composed of the same or a similar material as the insulator, and the metallic phase of which is composed of a material having good electrical conductivity. Since the material properties of the cermet are similar to those of the insulator—the thermal expansion, in particular, is same—a particularly good seal is created between the cermet and insulating body.

    • A glass ceramic, for use as a resistor or a gas-tight glass ceramic solder for use in a spark plug, includes a fused seal of a starting glass fused from a starting mixture containing SiO2, Al2O3, TiO2 and CaO, the fused seal including crystalline phases in at least some areas. A method for producing such a glass ceramic provides for the starting glass to be processed in a first method step to form a starting material, which is heated for a first period of time in a second method step from a starting temperature, which is below the softening temperature of the starting glass, to a fusion temperature, which is above the softening temperature of the starting glass, and is kept at that temperature for a second period of time and finally is cooled again. A spark plug may include a terminal stud and a center electrode, which are electrically connected across a resistor that is formed in at least some areas by the glass ceramic.

    • To securely seat a ceramic electrode (23, 28) in an insulator (15) of a spark plug, so that it can be sintered together with the insulator, a ceramic plug element (28) has added thereto an additive which renders the ceramic plastically deformable upon application of external energy; the additive may, for example, be a thermoplastic, which permits plastic deformation upon application of heat; or a thixotropic agent, such as glycerin, rendering the material plastically deformable when vibrated. A pellet or plug (28) is introduced into the end portion (32) of the central opening (21) of the insulator, preshaped to be slightly smaller by, for example, 0.2 mm, than the clearance opening in the insulator. The plug is then rendered plastically deformable, compressed by a plunger (34/1) acting against a counter plate (33). Either the plug or the inner surface of the bore can be coated with a conductive coating (27) including a burn-spark-resistant metal, for example platinum, which, upon compression, is not electrically interrupted. In subsequent heating steps, the additive is vaporized-off, and the plug sintered to the ceramic body which, initially, was only presintered.
    • 为了将陶瓷电极(23,28)牢固地安置在火花塞的绝缘体(15)中,使得其可以与绝缘体一起烧结,陶瓷插塞元件(28)已经添加了添加剂,使陶瓷塑性 施加外部能量时可变形; 添加剂可以是例如热塑性塑料,其在施加热量时允许塑性变形; 或触变剂,例如甘油,使材料在振动时可塑性变形。 将颗粒或塞子(28)引入到绝缘体的中心开口(21)的端部(32)中,预先形成比绝缘体中的间隙开口小例如0.2mm。 然后,塞子被塑性变形,通过作用在对抗板(33)上的柱塞(34/1)压缩。 孔的塞子或内表面可以涂覆有包括耐燃烧火花的金属(例如铂)的导电涂层(27),其在压缩时不被电中断。 在随后的加热步骤中,将添加剂蒸发掉,并将塞子烧结到陶瓷体上,其最初仅被预烧结。
