Abstract

The brazing technology for ceramic materials on the basis of BaTiO3 between itself and with metals, and also a method of platting of coating with high adhesion both for ferroelectric barium titanate using metal melts which contain elements with high affinity to electron (the brazing in the air atmosphere), and for semiconducting BaTiO3 with addition of chemically active transitive metals (in the vacuum conditions) is developed. The developed technologies allow to increase considerably adhesive strength of coating and brazing connections, and also expand and open new opportunities of creation of various devices: small-sized condensers with high capacity, piezoelectric and electrostrictive modules, acoustic devices, thermistors, etc.
