Abstract
Procédé de préparation de fibres creuses monolithiques essentiellement minérales et nouveaux produits ainsi obtenus. Dans ce procédé, on prépare une solution d'un polymère organique formant des fibres, contenant, sous forme dispersée, une matière minérale frittable, on extrude la solution de polymère à travers une filière, on forme une fibre creuse polymère, chargée de matière minérale, ayant une structure de paroi à volume de vides internes, radialement anisotrope, on traite cette fibre pour retirer le polymère organique, et on fritte la matière minérale résultante. La présente invention est particulièrement utile pour fournir des fibres creuses monolithiques notamment employées dans des électrodes pour des piles à combustible.
