What is Fumed Silica?
The Uses of Fumed Silica
Synthetic Amorphous Silica has interesting thickening and thixotropic properties, and an enormous external surface area. It is produced by a vapor phase hydrolysis process using chlorosilanes or substituted silanes such as, silicon tetrachloride in a flame of hydrogen and oxygen. This material is formed and collected in a dry state. This product contains no detectable crystalline silica.
What are the applications of Application
Silica, fumed is A chemical used in the synthesis of silicalite and in the catalytic growth of oxide and nitride nanowires.2
