Abstract:
A process for preparing a carbon species partially or completely covered with silica, including: bringing the carbon species into contact, in an aqueous medium, with one or more cationic surfactants, adjusting the pH of the reaction medium of the suspension using an alkaline agent to a pH that varies from 8 to 10, adding one or more alkali metal silicates to the reaction medium obtained, while maintaining the pH of the reaction medium between 8 and 10.
