Abstract
(EN)
Ceramic bodies may be prepared using a combination of thin structure formation techniques and metal oxidation techniques. Specifically, a thin form is provided comprising at least one parent metal, at least one organic or inorganic fiber, and optionally comprising at least one inorganic filler material. The thin form may then be infiltrated with a liquid or fusible composition such as a polyureasilazane to increase the flexibility and formability of the thin form. The thin form may then be shaped or configured, either individually or in stacks, and rigidized to form for example, a self-supporting structure. The thin form may then be heated to a temperature above the melting point of the parent metal to react the molten parent metal in situ with an oxidant to form an oxidation reaction product, which is at least partially three-dimensionally interconnected to form a thin ceramic body in a desired shape or configuration.

L'invention concerne la préparation de corps céramiques utilisant une combinaison de techniques de réalisation de structures minces et des techniques d'oxydation de métaux. Plus précisément, la forme mince de l'invention comprend au moins un métal de base, au moins un type de fibres organiques ou minérales et, éventuellement, au moins une charge minérale. La forme mince peut alors être infiltrée avec un liquide ou une composition fusible telle qu'un polyuréosilazane, pour augmenter la flexibilité et l'aptitude au formage de la forme mince. La forme mince peut alors être formée ou configurée, soit individuellement, soit en empilements, et rendue rigide pour former, par exemple, une structure autoportante. La forme mince peut alors être chauffée à une température supérieure au point de fusion du métal de base pour faire réagir le métal de base fondu in situ avec un oxydant et obtenir un produit de réaction d'oxydation, qui comporte des liaisons tridimensionnelles au moins partielles. On réalise ainsi un corps céramique mince de la forme ou de la configuration souhaitée.
