Patent DE-2444779-A1 (DE)
Inventor: PITHA JOHN JOSEPH
IPC: H01C7/10
Filed: 1974-09-19
Abstract: To produce at least one electrode on a porous ceramic object, either a layer containing finely disperse titanium oxide or a layer containing titanium oxide and an additional metal oxide which is more readily reducible than titanium oxide, can be applied to the surface of the porous granular substrate. The substrate with the applied layer is then heated in a reducing atmosphere to a temperature between 1200 and 1300 DEG C until the titanium oxide has been reduced to an extent greater than that corresponding to its stoichiometric state. As a result, it becomes relatively conductive. The coated substrate is finally cooled to room temperature. The novel electrode is suitable above all as an overvoltage protection of components, for example in surge voltage arresters. <IMAGE>
