Abstract
LA PRESENTE INVENCION SE REFIERE A UN PROCESO PARA LA PREPARACION DE OXIDOS POROSOS MEZCLADOS CON UNA MORFOLOGIA ESFERICA Y LOS OXIDOS ELLOS MISMOS OBTENIDOS DE ESTA MANERA. ESTE PROCESO CONSISTE EN EMULSIONAR, EN UN AMBIENTE ACIDO, UN SOL MEZCLADO CON UN MEDIO DISPERSANTE, GELIFICAR LA MICROEMULSION FORMADA DE ESTA MANERA POR CONTACTO CON UNA DISOLUCION ALCALINA Y SOMETER EL GEL OBTENIDO A ENVEJECIMIENTO TERMAL EN PRESENCIA DEL LIQUIDO EMULSIONANTE Y DE LA BASE DE GELACION DEL SOL O EN UN MEDIO DE AGUA BAJO CONDICIONES CONTROLADAS DE PH Y TEMPERATURA. LOS OXIDOS MEZCLADOS ANTERIORMENTE PUEDEN SER APLICADOS COMO PORTADORES PARA CATALIZADORES O COMO PRECURSORES DE MATERIALES CERAMICOS.
