Abstract

L'invention concerne un agent de dispersion qui est utilisé pour obtenir une composition de céramique malaxée qui présente un effort d'extrusion réduit et une bonne aptitude au moulage, même lorsque la vitesse d'extrusion est augmentée. L'invention concerne de manière spécifique un agent de dispersion qui est utilisé dans une composition de céramique malaxée dans un procédé destiné à produire un produit de céramique qui comprend un procédé destiné à mouler par extrusion la composition de céramique malaxée. L'invention concerne également une composition de céramique malaxée, un procédé destiné à extruder une composition de céramique malaxée, un produit de céramique et un procédé destiné à produire un produit de céramique.
