A method for high temperature resistant connection of the oxygen - permeable oxide ceramics on the basis of substituted erdalkalicobaltate by means of doping an diffusive reaction sintering under

摘要

The invention relates to a method for high temperature resistant connection or joining of oxide ceramic components made from conductive mixed oxide ceramics.The object of the invention is to provide a possibility, with the refractory compounds of ceramic components from mixed conductive substituted erdalkalicobaltaten can be made, for which, when using a dense membrane components these compounds are to be in a gas-tight manner.The problem is solved with a method for high temperature resistant connection of the oxygen - permeable oxide ceramics on the basis of which is unsubstituted or substituted by doping erdalkalicobaltate under an diffusive reaction sintering is achieved in that at least one of the joining surfaces with cu - containing additives and then be provided under load by weight or other forces be heated up to temperatures of up to 250 k under the usual sintering temperature of the ceramic components are present at this temperature and 0,5 hours to 10 hours is held.
