Abstract (en)

[origin: WO9421015A1] The proposal is for an electrically conductive sealing compound for a set of contacts for sparking plugs which is arranged between the terminal and ignition sides of a central electrode, the sealing compound containing essentially a meltable glass component and a powdered electrically conductive component. The electrically conductive component of the sealing compound consists solely of graphite and represents 10 to 30 vol. % in relation to the powdered components of the sealing compound.
