Verfahren zum Herstellen eines Keramik-Metall-Verbundsubstrats und Hartlotwerkstoff zum Verwenden in diesem Verfahren

摘要

In the present invention, a metal-ceramic composite substrate is produced by joining a metal plate and a ceramic substrate by using a brazing alloy material of which the solid content comprises Ag in an amount of 90.0%-99.5%, and an active metal in an amount of 0.5-4.0% on a weight basis. The brazing alloy material may further comprise Cu in an amount of up to 9.5% and titanium oxide in an amount of up to 0.9%.
