FIELD: metallurgy.
SUBSTANCE: invention relates to a method of obtaining glass-to-metal and metal-ceramic compounds and metal-metal compounds used in solid oxide fuel cells. According to the invention, the compounds are obtained by using a mixture of powders of base glass and metal oxide. Adding some components to the glass used in the composite joints, for instance MgO, that influence on its viscosity and wetting ability ensures a local change in the glass properties near the interface with the metal and at the same time making glass bulk properties including increased coefficient of thermal expansion closer to the properties of the other components of the joint.
EFFECT: high performance, durability and operating safety of the fuel cells.
