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...
