Oarsil is amorphous fumed silica produced by vapor phase hydrolysis ysis of silicon tetrachl in flame of hydrogen and oxygen, the resulting products arepure, xray amorphous, silicon dioxide(Sio2) the chemical reaction for this process is:




Silica particle morphology can be modified by variations in flame conditions

The B.E.T Surface Area is the quantitative characteristic that def-ines the different grades of Oarsil.

Oarsil is produced in accordance with Q/(GZ)GBS01-2002


Oarsil is a pure amorphous pyrogenic silica. The appearance of the non-toxic and is not flammable or combustible.


Packing and transport
