PATENT-ANSPRÜCHE :
1. Stabförmiges elektrisches Heizelement zur Erzeugung hoher Temperaturen, insbesondere in elektrischen Ofen, dessen aus Wolfram, Molybdän oder einem andern, ähnlich hochschmelzenden Widerstandsmaterial bestehender Heizleiter in einer gegen den Aussenraum abgeschlossenen rohrförmigen keramischen Umhüllung in indifferenter Atmosphäre oder im Vakuum angeordnet ist, dadurch gekennzeichnet, dass die zur Herstellung des keramischen Rohres verwendete Masse Aluminiumsilikate und/oder Magnesiumsilikate enthält und dass die Rohrenden durch Metallkappen verschlossen sind, die unter Verwendung eines Hartlots mit dem keramischen Rohr vakuumdicht verbunden sind.

can also be cooled well, in particular by moving a liquid or gaseous coolant past them.
PATENT CLAIMS:
1. Rod-shaped electrical heating element for generating high temperatures, in particular in an electric furnace, whose heating conductor, made of tungsten, molybdenum or another similar high-melting resistance material, is arranged in a tubular ceramic envelope closed off from the exterior in an inert atmosphere or in a vacuum, characterized in that that the mass used to manufacture the ceramic pipe contains aluminum silicates and / or magnesium silicates and that the pipe ends are closed by metal caps which are connected to the ceramic pipe in a vacuum-tight manner using a hard solder.
