A process for joining at least two substrates together comprises applying between the substrates a composition comprising a liquid pre-ceramic binder and at least one other component selected from a metal powder, a metal oxide powder and mixtures thereof, and pyrolysing the composition, to form a join between the two substrates, the join comprising a mixed metal oxide. The composition is capable of joining together a wide variety of substrates, without failure, after exposure to high temperature.
L'invention concerne un procédé d'assemblage d'au moins deux substrats, caractérisé en ce qu'on applique entre les substrats une composition comprenant un liant liquide pré-céramique et au moins un autre composant pouvant être une poudre métallique, une poudre d'oxyde métallique et des mélanges de celles-ci, en ce qu'on pyrolyse la composition de manière à former un joint entre les deux substrats, ledit joint comprenant un oxyde métallique mixte. La composition permet de réaliser l'assemblage d'une grande variété de substrats, sans aucun défaut, après exposition à des températures élevées.
