SOLDER MATERIAL FOR FASTENING AN OUTER ELECTRODE ON A PIEZOELECTRIC COMPONENT AND PIEZOELECTRIC COMPONENT COMPRISING A SOLDER MATERIAL

摘要

The invention relates to a solder material (6, 6a, 6b) for fastening an outer electrode (7, 71a, 71b, 72a, 72b) on a piezoelectric component (1). The solder material (6, 6a, 6b) contains tin as the main constituent and at least one addition of the group consisting of cobalt, tungsten, osmium, titanium, vanadium, iron and rare earth metals. The invention further relates to a piezoelectric component (1) comprising such a solder material (6, 6a, 6b), wherein the solder material (6, 6a, 6b) is applied by means of a base metallization (4).
