Abstract

Una hoja de óxido de aluminio que tiene dos caras mayores sensiblemente paralelas con poros que van de una cara de la lámina a la otra, incluyendo una disposición de poros mayores que se extienden desde una cara al interior de la hoja y una disposición da poros menores que se extienden hacia dentro desde la otra cara, interconectándose la disposición de poros mayores con la disposición de poros menores de manera que los extremos interiores de uno o más poros menores se unen al extremo interior de un poro mayor y no existen en esencia poros mayores ciegos.
