Ultrafine Silica Powder. David Yvon. The use of silica powder. Business Articles | June 21, 2012. The silica powder is an important raw material for the production of polysilicon. Silica powder reacts with anhydrous hydrogen chloride in a fluidized bed reactor. It generates trichlorosilane.

12/12/2016 · Ultrafine Silica Powder (commonly known as superfine white carbon black) is a white, nontoxic, tasteless and amorphous inorganic fine chemical product, which is made through chlorosilane's hydrolysis process in high temperature oxyhydrogen flame. By adjusting the process conditions, silica powder's primary particle size can be produced as ...

Micro silica also known as fume, is an amorphous (noncrystalline) polymorph of silicon dioxide, is an ultrafine powder collected as a byproduct of the silicon ferrosilicon alloy production consists of spherical particles with an average particle diameter of 150 mm.
