Abstract

L'invention concerne des liants de fonderie thermodurcis constitués d'un mélange (1) d'une source de silice soluble et (2) d'une source d'alumine soluble, de manière que la source de silice, la source d'alumine ou les deux contiennent un métal alcalin. Les constituants des liants forment une solution saturée quand on les mélange avec un agrégat. On façonne et on chauffe le mélange obtenu à température élevée, afin de réaliser une forme de fonderie durcie. On applique de la chaleur au moyen d'air chaud, on effectue une cuisson dans un four, sous micro-ondes et, de préférence, dans une boîte à noyau réchauffée.
