Abstract

L'objet de l' invention est un procédé de réalisation d'un élément poreux en céramique pour la diffusion d'eau pour l'arrosage, ledit procédé comprenant une étape de moulage sous pression d'une barbotine puis une étape de cuisson, caractérisé en ce que la barbotine comprend de 10 à 40 % de silices dont 30 à 100 % d'une silice avec une répartition granulométrique d'un premier type et 0 à 70% d'une silice avec une répartition granulométrique d'un second type avec un pourcentage de fines de gros diamètres plus important que la répartition granulométrique du premier type.
