Abstract[English]
An aqueous suspension for producing porous metallic structures comprises 2-49 vol% of a mixture of at least one chemical compound comprising a metal atom, wherein said at least one compound is solid at room temperature, has the form of a powder, and is suspended in water, and 10-9 to 0.1 mol of a surfactant per mol of said chemical compound comprising a metal atom. The aqueous suspension is part of a foam and/or is part of an oil-in-water emulsion, comprising 30-90 vol% of a lipophilic phase, said lipophilic phase not comprising a polymerizable compound.[French]
Une suspension aqueuse pour la production de structures métalliques poreuses comprend de 2 à 49 % en volume d'un mélange d'au moins un composé chimique comprenant un atome métallique, ledit au moins un composé étant solide à température ambiante, ayant la forme d'une poudre, et étant en suspension dans l'eau, et de 10-9 à 0,1 mole d'un tensioactif par mole dudit composé chimique comprenant un atome métallique. La suspension aqueuse fait partie d'une mousse et/ou fait partie d'une émulsion huile-dans-eau, comprenant de 30 à 90 % en volume d'une phase lipophile, ladite phase lipophile ne comprenant pas de composé polymérisable.
