Abstract
The technology for brazing in air environment and commercially pure oxygen atmosphere as well as method for deposition of coatings using metal melts with high degree of wettability of ceramics have been developed for the BaTiO₃-base ferroelectric ceramics. The technology developed makes it possible to substantially increase adhesion strength of coatings and brazed joints, widen existing and open new possibilities for manufacture of different instruments and devices.
