Abstract

SILICE COMPATIBLE CON IONES METALICOS, TALS COMO CINC, ESTAÑO O ESTRONCIO, CARACTERIZADA POR UN NUMERO DE OH DE SUPERFICIE EXPRESADO EN OH/NM2 INFERIOR O IGUAL A 10, UN PUNTO DE CARGA NULA (PZC) COMPRENDIDO ENTRE 3 Y 6,5 Y QUE DA UNA SUSPENSION ACUOSA CUYO PH VARIA EN FUNCION DE SU CONDUCTIVIDAD ELECTRICA SEGUN LA ECUACION: PH = B - ALOG(D), EN LA QUE A ES UNA CONSTANTE INFERIOR O IGUAL A 0,6, B ES UNA CONSTANTE INFERIOR O IGUAL A 8,5 Y (D) REPRESENTA LA CONDUCTIVIDAD ELECTRICA DE LA SUSPENSION ACUOSA DE SILICE EXPRESADA EN MICROSIEMENS/CM. PROCEDIMIENTO PARA PREPARACION DE LA SILICE QUE CONSISTE EN HACER REACCIONAR UN SILICATO CON UN ACIDO CONDUCIENDO ASI A UNA SUSPENSION O UN GEL DE SILICE, EFECTUAR UNA PRIMERA MADURACION A UN PH SUPERIOR O IGUAL A 6 E INFERIOR O IGUAL A 8,5, Y DESPUES UNA SEGUNDA MADURACION A UN PH INFERIOR O IGUAL A 5,0; SEPARAR LA SILICE; SOMETERLA A UN LAVADO CON AGUA CALIENTE HASTA QUE SE OBTIENE UNA SUSPENSION ACUOSA CUYO PH MEDIDO EN UNA SUSPENSION DE 20 % DE SILICE RESPONDE A LA ECUACION: PH = D - CLOG(D), EN LA QUE C ES UNA CONSTANTE INFERIOR O IGUAL A 1,0, D ES UNA CONSTANTE INFERIOR O IGUAL A 8,5, Y (D) REPRESENTA LA CONDUCTIVIDAD ELECTRICA DE LA SUSPENSION ACUOSA DE SILICE EXPRESADA EN MICROSIEMENS/CM; FINALMENTE SECAR. COMPOSICION DENTRIFICA QUE CONTIENE LA SILICE DESCRITA.
