Abstract (en)
[origin: DE19853844A1] A spark plug has a temperature resistant, low thermal expansion sealant (16) containing ceramic and metallic components. A novel spark plug has a central electrode (14) sealed in an insulator (11) by a temperature resistant sealant (16) containing a metallic component of melting temperature above the service temperature and a ceramic component exhibiting low thermal expansion.
