Verfahren zur Herstellung von gasdichten und hochtemperaturbeständigen Verbindungen von Formteilen aus nichtoxidischer Keramik mittels Laser

Ceramic solder is a mixture with the following composition, expressed in percentages by weight: yttrium oxide 80-30 and/or zirconium oxide 55-15; aluminum oxide 5-70; silicon dioxide 0-50; silicon 0-10. A laser is employed to reach fusing temperature. No protective atmosphere or vacuum is used to ma...

More Information
Summary:Ceramic solder is a mixture with the following composition, expressed in percentages by weight: yttrium oxide 80-30 and/or zirconium oxide 55-15; aluminum oxide 5-70; silicon dioxide 0-50; silicon 0-10. A laser is employed to reach fusing temperature. No protective atmosphere or vacuum is used to make the joint. Adequate wetting of the joined surfaces is achieved through silica. This arises from one or more of: the ceramic, the ceramic solder and/or additional silica coating at the joint.
