Abstract

La invención se relaciona con sílices precipitadas que tienen los siguientes parámetros fisicoquímicos: CTAB de 50 m2/g - 450 m2/g, relación de BET/CTAB < 1.3, factor de cola de 5% = 150 nm. Las sílices precipitadas se producen haciendo reaccionar vidrio soluble con H2SO4 utilizando varios pasos de envejecimiento. Las sílices precipitadas pueden utilizarse para la producción de mezclas de caucho.
