Description
Die Erfindung bezieht sich auf weiche, d. h. niedrig schmelzende Gläser, die insbesondere zur Herstellung von Schmelzverbindungen zwischen Natrium-Kalk- und Bleigläsern geeignet sind.The invention relates to soft, i. H. low-melting glasses, which are particularly suitable for Manufacture of fusion connections between sodium-lime and lead glasses are suitable.
Gläser nach Art der Soda-Kalk-Gläser oder Bleigläser, mit denen die Gläser gemäß vorliegender Erfindung verwandt sind, besitzen eine thermische Ausdehnung in der Größenordnung von 90 X io~7. Sie erweichen bei Temperaturen von etwa 6oo° C. Wenn zwei Teile, die aus Soda-Kalk- oder Bleiglas bestehen, miteinander vereinigt werden sollen, ist es zweckmäßig, zwischen den zu vereinigenden Teilen eine Glaszwischenschicht anzubringen, die bei wesentlich niedrigerer Temperatur flüssig wird, als bei der Erweichungstemperatur der zu vereinigenden Teile. Hierdurch wird die Verformung der zu verbindenden Teile vermieden, die eintreten würde, wenn diese Teile miteinander durch Erhitzung derselben über die Erweichungstemperatur verbunden und dann im noch flüssigen Zustand zusammengepreßt werden. Die Glaszwischenschicht oder Verbindungsschicht muß zweckmäßig einen Ausdehnungskoeffizienten besitzen, der ähnlich denjenigen des Glases oder der Gläser ist, aus denen die zu vereinigenden Teile bestehen.Glasses of the type of soda-lime glasses or lead glasses, to which the glasses according to the present invention are related, have a thermal expansion in the order of magnitude of 90 × 10 ~ 7 . They soften at temperatures of around 600 ° C. If two parts made of soda-lime or lead glass are to be combined, it is advisable to apply an intermediate glass layer between the parts to be combined, which becomes liquid at a much lower temperature, than at the softening temperature of the parts to be united. This avoids the deformation of the parts to be connected, which would occur if these parts are connected to one another by heating them above the softening temperature and then pressed together in the still liquid state. The intermediate glass layer or connecting layer must expediently have a coefficient of expansion which is similar to that of the glass or glasses of which the parts to be combined are made.
Die Erfindung bezweckt, einen Bereich von Gläsern zu schaffen, die bei Temperaturen, die 5500C nicht übersteigen, flüssig werden und sich deshalb besonders eignen, Natrium-Kalk-Gläser oder Bleigläser miteinander zu verbinden, die eine höhere Erweichungstemperatur und dabei eine thermische Ausdehnung in der obenerwähnten Größenordnung besitzen.The aim of the invention is to create a range of glasses that become liquid at temperatures not exceeding 550 ° C. and are therefore particularly suitable for joining together sodium-lime glasses or lead glasses that have a higher softening temperature and thermal expansion in the order of magnitude mentioned above.
