Description

Lötverbindung zwischen-Quarz- und Metallrohr Die Erfindung betrifft eine Lötverbindung zwischen einem Quarzrohr und einem dazu axial fluchtenden Metallrohr. Soldered connection between quartz and metal tube The invention relates to a soldered connection between a quartz tube and a metal tube axially aligned with it.

Es ist bekannt, daß Lötverbindungen dieser Art besonders zerbrechlich sind wegen des unterschiedlichen Temperaturverhaltens der beiden Materialien. Daher hat man bisher gelegentlie" @:.uchti den Fuß des Quarzrohres durch Anschweißen von mehreren Glas-ing mit sich langsam ändernden Ausdehnungskoeffizienten allmählich an das Temperaturverhalten des Metallrohres anzupassen. Aber selbst bei diesem komplizierten Verfahren waren Brüche des äußerst fragilen ein, benetzt die Kontaktflächen von Quarzfuas Metallrohr und Metallring und verbinde: beide miteinander,: Dann läßt man die erhaltene Lötverbindung im Ofen während ca. 2 S Bunden langsam abkühlen. It is known that soldered connections of this type are particularly fragile because of the different temperature behavior of the two materials. Therefore, up to now one has occasionally had to gradually adapt the base of the quartz tube to the temperature behavior of the metal tube by welding on several glass-ing with slowly changing coefficients of expansion . But even with this complicated process, fractures of the extremely fragile were one, wets the contact surfaces of quartzfua's metal tube and metal ring and connect: both to one another: Then the soldered joint obtained is allowed to cool slowly in the oven for approx. 2 ½ coils.

Durch die beschriebene Lötung -wird nicht nur die mechanische Ver-Bindung von Quarzrohr und Tragrohr erreich-, sondern auch die Vakuumdichtheit; dafür sorgt die gute Benetzung von Titan auf Quarz Die konische Formgebung des Rohrfußes und die zugehörige trichterförmige Erweiterung des Metallrohres tragen der radialen und axialen Ausdehnung vor. Quarzrohr und Metallrohr Rechnung, sowie der optimalen .Rene tzung der Kontaktflüchen., Das folgende praktische Beispiel soll zeige::, daß die erfindungs- gemäße Lötverbindung zu dem gewünschten Erfolg führt: Außendurchmesser des tdulstes 19,5 mm Innendurchmesser des Quarzrohres $ mm Innendurchmesser des Randbereichs des Metallrchr s 1e - '% mm Außendurchmesser des Quarzrahrs 10 mm Innendurchmesser des Metallrohrs 11,5 mm Wandstärke des Randbereichs des Metallrohrs 0,1 mm Höhe des Randbereichs 3,5 mm Höhe der Wulstoberkante über dem Ende des Quarzrohrs 3 mm Wandstärke der trichterförmigen Erweiterung und des an-schließenden Metallrohrteils 0,2 mm The described soldering not only achieves the mechanical connection of the quartz tube and the support tube, but also the vacuum tightness; this is ensured by the good wetting of titanium on quartz. The conical shape of the tube base and the associated funnel-shaped extension of the metal tube contribute to the radial and axial expansion. Quartz tube and metal tube calculation, as well as the optimal .Renzung the contact areas., The following practical example should show: that the inventive soldered connection leads to the desired success: Outside diameter of the tdulstes 19.5 mm inside diameter of the quartz tube $ mm inside diameter of the Edge area of the metal tube 1e - '% mm outer diameter of the quartz tube 10 mm inner diameter of the metal tube 11.5 mm wall thickness of the edge area of the metal tube 0.1 mm height of the edge area 3.5 mm height of the bead top edge above the end of the quartz tube 3 mm wall thickness of the funnel-shaped expansion and subsequent metal tube part 0.2 mm
