Silicon dioxide with CAS 112945-52-5

what is of  Silicon dioxide with CAS 112945-52-5?

Fumed silica may be synthesized by high temperature hydrolysis of SiCl4 in O2(N2)/H2 flame. It is amorphous in nature and possesses very high specific area. The micro droplets of amorphous silica fuse into a branch and form a chain like agglomerate.

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.
