  Verfahren zur   Erhöhung   der   Widerstandsfähigkeit   von Zündkerzen. 



   Den Gegenstand vorliegender Erfindung bildet ein Verfahren, der gebrechlichen Isoliersehichte der Zündkerzen für Explosionsmotore sowohl gegen mechanische   Beanspiuehung,   wie auch gegen die Temperaturschwankungen einen grösseren Widerstand zu verleihen. Zu diesem Zwecke werden der keramischen Masse der Isolierschichte vor dem Brennen   Meta. Iloxyde   oder Metallsalze beigemischt. 



    Ähnliche Metallverbindungen   werden bereits zum Zwecke der Färbung von Porzellanmassen verwendet : dieses Verfahren wurde aber nur bei reduzierendem Feuer durchgeführt. Bei den bisher verwendeten Materialien für die   Isoliersehichte,   wie Porzellan, Sandstein, Steatit oder Mischungen dieser Körper mit

 grösster Sorgfalt nicht   gelöst   werden.   E3     wmde nun festgestellt,   dass eine Beigabe von Metallsalzen, welche zwischen 1 und   10% und   mehr, je nach dem verwendeten Material schwanken kann, ein Produkt ergibt, welches einen beträchtlichen Widerstand gegen mechanische Beanspruchungen und Temperatur-   Schwankungen   leistet, ohne im mindesten seine Isolierfähigkeit einzubüssen.

   Es wurde festgestellt, dass insbesondere die Oxyde oder Salze   Ize von Mansan. Eisen und   besonders die des Kobalts. Kupfers und des Zinks das angestrebte Ziel erreichen lassen. Das Brennen erfolgt dabei in einer nicht reduzierenden   Atmosphäre.

  Process for increasing the resistance of spark plugs.



   The subject matter of the present invention is a method to give the fragile insulating layer of the spark plugs for explosion engines a greater resistance both to mechanical stress and to temperature fluctuations. For this purpose, the ceramic mass of the insulating layer is meta before firing. Iloxides or metal salts are added.



    Similar metal compounds are already used for the purpose of coloring porcelain bodies: this process was only carried out with a reducing fire. With the materials previously used for the insulating layer, such as porcelain, sandstone, steatite or mixtures of these bodies

 greatest care not be resolved. It has now been found that the addition of metal salts, which can vary between 1 and 10% and more, depending on the material used, results in a product which offers considerable resistance to mechanical stresses and temperature fluctuations, without at least its insulating capacity to forfeit.

   It was found that in particular the oxides or salts Ize of Mansan. Iron and especially that of cobalt. Let copper and zinc achieve the aimed at goal. The firing takes place in a non-reducing atmosphere.
