Abstract

L'invention concerne un corps poreux céramique approprié pour la filtration de métaux en fusion. Le corps poreux céramique selon l'invention présente une structure cellulaire à réseau tridimensionnel pourvue de nombreux vides interconnectés et sans obstruction dans aucune direction, il a une dimension de pores correspondant à 25-35 pores par centimètre linéaire, apparaissant dans une aire de coupe choisie librement, une densité apparente comprise entre 0,3 et 0,7, une porosité comprise entre 75 et 90 %, et une perte de pression de 4,8 à 30,0 mm au manomètre à eau lors du passage d'air au travers dudit corps de 1 cm d'épaisseur à une vitesse de 1 m/s. Application : filtration de métaux fondus.
