Ewende Silica Fume

Silica Fume, also known as Micro Silica Fume, Micro Silica Powder, Micro Silica, Microsilica,Silicafume, Silicone Powder, Microsilicon, Powdered Silicon, Microsilica, Silica Fume Powder, Silica Powder, Silicon Powder, Silicium Powder, Silica Dust is an amorphous (non-crystalline) polymorph of silicon dioxide, silica. It is an ultrafine powder collected as a by-product during silicon and ferrosilicon alloy production.

With the implementation of tougher environmental laws during the mid-1970s, silicon smelters began to collect the silica fume and search for its applications. The early work done in Norway received most of the attention since it had shown that Portland cement-based-concretes containing silica fumes had very high strengths and low porosities. Since then the research and development of silica fume made it one of the world’s most valuable and versatile admixtures for concrete and cementitious products.

Silica fume powder is black or gray in color and is available in several product forms and packaging options. Our products include:Undensified Silica Fume ( 300~380kg/m³) and Densified Silica Fume ( 600~680 kg/m³)

Undensified Silica Fume

Undensified Silica Fume, which is made from a large amount of highly volatile silicon monoxide gas produced during the smelting process, is rapidly oxidized with air and condensed into silica dust.

Densified Silica Fume

Densified Silica Fume, is a further processing of the original micro silica fume to obtain a denser encrypted micro silica fume.
