Abstract

La présente invention a pour objet de nouvelles compo­ sitions pour moules et noyaux en fonderie, liées par un liant à base de silicates.
Elle se caractérise par le fait que l'agent de débourrage compren un dérivé minéral métallique, notamment du groupe des alcalino-terreux, sous forme d'une poudre fine et de l'alumine.
Elle s'applique en fonderie.
