This metal paste preferably contains an additive such as a surfactant in accordance with the application method. As a sealing method using this metal paste, there is a method of applying and drying a metal paste, sintering it at 80 to 300° C. to form a metal powder sintered body and after that pressurizing the base member and the cap member while heating the metal powder sintered body."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Metal paste for sealing, hermetic sealing method for piezoelectric element, and piezoelectric device","description":"The present invention is a metal paste for sealing comprising a metal powder and an organic solvent characterized in that the metal powder is one or more kinds of metal powders selected from a gold po","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8505804","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
