Abstract

Grafting reaction of methyltriethoxysilane on sepiolite surface was studied. The structure of the salinized product before and after thermal treatment was characterized by XRD, TG-DTA, SEM and IR. It is found that the silicon monomers are grafted on the external surface of sepiolite via silicon hydroxyls. The thermal stability remains unchanged after silanization.
