    Abstract: Method for producing by laser gastight and high-temperature resistant connections of shaped parts made of non-oxidic ceramic. The invention relates to the fields of ceramics and laser technology and relates to a method with which, e.g., low-melting-point or radioactive materials can be enclosed inside a container made of ceramic. The object of the invention is to produce a durable, gastight and high-temperature resistant connection between components made of non-oxidic ceramic. Shaped parts made of the ceramic are provided on the surfaces to be joined with a solder of 80-30% by weight yttrium oxide and/or 55-15% by weight zirconium oxide, 20-70% by weight aluminum oxide, 0-50% by weight silicon dioxide and 0-10% by weight silicon, and subsequently the temperature at the joint area is increased above the melting temperature of the solder by means of a laser without the presence of a protective gas atmosphere or a vacuum.
