Abstract

SE PRESENTA UN TAMIZ MOLECULAR QUE COMPRENDE CRISTALES O AGLOMERADOS DE UN DIAMETRO MEDIO DE 100 NANOMETROS O INFERIOR, DICHO TAMIZ MOLECULAR TIENE UNA DISTRIBUCION DE TAMAÑO DE CRISTALES O AGLOMERADOS TAL QUE LA VARIANCIA EN LA DIMENSION MAS GRANDE ES INFERIOR AL 15% DE LA DIMENSION MEDIA MAS GRANDE, Y QUE ES CAPAZ DE FORMAR UNA SUSPENSION COLOIDAL, EL TAMIZ MOLECULAR PUEDE PREPARARSE MEDIANTE LA PRODUCCION DE UNA MEZCLA DE SINTESIS ACUOSA HIRVIENTE DE UNA FUENTE DE SILICE Y UN AGENTE ORGANICO DIRECTOR DE LA ESTRUCTURA EN LA FORMA DE UN HIDROXIDO EN UNA CANTIDAD SUFICIENTE COMO PARA PROVOCAR LA DISOLUCION SUBSTANCIALMENTE COMPLETA DE LA FUENTE DE SILICE, Y MEDIANTE LA CRISTALIZACION DE LA SOLUCION A 120 (GRADOS) C O MENOS. EL TAMAÑO DEL CRISTAL PUEDE CONTROLARSE MEDIANTE LA SELECCION DE UNA TEMPERATURA DE CRISTALIZACION APROPIADA.
