Abstract

La suspensión de precipitación original del ácido silícico de precipitación hidrófilo puede obtenerse como sigue: En un reactor se dispone previamente 1 parte en volumen de agua. Lentamente se añaden con agitación a lo dispuesto previamente 0,15 a 0,25 partes en volumen de solución de vidrio soluble (módulo SiO2 : Na2O = 3,5 y 26% de SiO2) y 0,015 a 0,025 partes en volumen de H2SO4 (al 96%), manteniéndose durante la adición en la mezcla un valor de pH alcalino. Después de la conclusión de la adición de vidrio soluble y de H2SO4 el valor de pH de la suspensión obtenida está en el margen débilmente alcalino.
