Category: Undensified Silica Fume

Silica fume, also known as microsilica, 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. According to the SiO2 content, our products can arrange form grade 85% to grade 96%. According to the bulk density, we can divide our products into densified silica fume and…

The application of unshaped castables refractories undensified silica fume: (1). Silica fume in Concrete . Can increacing strength, density . Frost resistance, Early strength, . abrasion resistance performance . anti-cavitations (2). Silica fume in Cement Strengthens the fibre cement product (3) Silica fume is used in refractory Greatly improved products strength and high temperature performance. (4) Other Applications for Silica…

Product name: Silica Fume / Microsilica Grade 90 Silica fume, a co-product from the production of silicon or ferrosilicon metal, is an amorphous silicon dioxide - SiO2 which is generated as a gas in submerged electrical arc furnaces during the reduction of very pure quartz.  This gas vapor is condensed in bag house collectors as very fine powder of spherical particles…
