Abstract

Método de producción de liogeles sustancialmente esféricos, en el que: a) se fabrica un liosol disponible b) el liosol obtenido en la etapa a) se transfiere al menos a un agente sililante en el que el liosol es insoluble, y c) el liosol esférico formado en la etapa b) se gelatiniza en al menos un agente sililante en el que el liosol es asimismo insoluble, para producir el liogel.
