METAL-CERAMIC BUILT-UP UNIT, A BUILT-UP FRAMEWORK FOR TRANSFER OF OXIDE IONS, A BUILT-UP UNIT HAVING A CAPABILITY OF SEALING Russian patent published in 2005 - IPC

FIELD: methods of sealing of built-up structures.

SUBSTANCE: the invention is pertaining to technologies of sealing of built-up structures. The invention offers a method of sealing, which makes it possible to form easily a sealing compaction, which has an exclusive reliability and a capability of repetition of a thermal cycle in the range of high temperatures of 800°C or higher. The offered built-up block contains: ceramics and a metal preferably used for a device intended for production of clear oxygen, the oxygen-rich air, etc.; a membranous reactor intended for the partial oxidation of a hydrocarbon gas; a solid-state oxidic fuel cell; a device of oxygen clearing; a heat exchanger or a similar device. The part of elements of the built-up unit is made out of an oxidic material and the tank is filled in with silver or a silver alloy. The offered invention ensures an increase of tightness of built-up frameworks. In particular, use of the units in the device intended for production of clear oxygen, the oxygen-rich air or in a similar device, in the membranous reactor for the partial oxidation of the hydrocarbon gas, in the solid-state oxidic fuel cell, in the oxygen clearing device, in the heat exchanger or in the similar device allows to speed-up significantly the production process.

EFFECT: the invention ensures an easy formation of a reliable tightness and significant speed-up of the production process.
