Procedimiento para el conformado de materiales cerámicos y/o metálicos por gelificación de carragenatos

Abstract

La presente invención se refiere a un procedimiento para el conformado de piezas de forma simple o compleja a partir de suspensiones acuosas, que comprende las etapas de preparación de una suspensión estable de los polvos cerámicos y/o metálicos en agua, la adición de un gelificante, bien en forma de polvo o disuelto previamente en agua, el llenado de un molde con la mezcla a una temperatura superior a la Tg, y el moldeo rápido por descenso de la temperatura por debajo de la Tg del aglomerante. Como aditivo gelificante se utilizan polisacáridos de la familia de los carragenatos. La invención es adecuada para el conformado de piezas por simple vertido de la mezcla en el molde o por métodos que utilizan presión, como el moldeo por inyección a baja presión.
