Abstract

La invención se refiere a un procedimiento para producir liógelas básicamente globulares, en el que los constituyentes que constituyen el gel se mezclan, después de lo cual se introduce liosol en un medio que se disuelva en el liosol de manera notable para formar el gel. La invención también se refiere a un procedimiento para producir aerogeles básicamente globulares, en el que las liógelas producidas de acuerdo con el procedimiento se convierten en un aerogel.
