Abstract

Procedimiento para la estabilización de percarbonato de sodio con compuestos que contienen ácido silícico, que se caracteriza porque en la primera etapa de procedimiento se aplica ácido silícico finamente distribuido sobre la superficie de percarbonato de sodio húmedo, que contiene de 1 hasta 10% en peso de agua, formándose en una segunda etapa de procedimiento, durante el desecado del agua que mantiene adherido al percarbonato de sodio, silicato de sodio como sustancia de recubrimiento sobre la superficie del percarbonato de sodio.
