Abstract

Procédé et appareil pour fritter une masse de matériau en particules. Le procédé comprend les étapes suivantes : a. Appliquer une première pression à la masse dans une première direction; b. Appliquer une seconde pression à la masse dans une seconde direction qui est transversale à la première; c. Appliquer une troisième direction qui est transversale aux première et seconde directions; et d. Modifier successivement au moins deux des première, seconde et troisième pressions et cela cycliquement pendant que la masse est chauffée à une température de frittage.
