Abstract
Fabricación en continuo de artículos cerámicos y/o metálicos por extrusión-gelificación de suspensiones acuosas. La presente invención se refiere a un método de conformado en continuo de piezas de sección transversal constante y de bajo espesor de pared basado en la extrusión de suspensiones acuosas que contienen polisacáridos y posterior gelificación de estos por enfriamiento a la salida de la boquilla o por polimerización química.
