Abstract

<B>PROCESSO PARA PRODUZIR SìLICA COLOIDAL SILANIZADA<D> é revelado um método para preparar uma suspensão aquosa de partículas de sílica coloidal organo-silanizada. Tais partículas são utilizadas em uma variedade de aplicações, incluindo meio de separação de gradiente de densidade, revestimentos anti-abrasivos e materiais para toners. O processo revelado é ambientalmente seguro e gera um produto aquoso e não-tóxico para a maioria das células biológicas.
