Abstract

L'invention se rapporte à la fabrication de pièces à partir d'un matériau en particules. Elle se caractérise par un chauffage 11 de corps 1 façonné, avant sa cuisson, pour en liquéfier le liant, dans un environnement 9 de solvant 19 en phase vapeur, ce qui permet la dissolution du liant sans contraintes excessives. L'invention s'applique notamment à des céramiques et à des métaux frittés.
