Microsilica Fume, alternately named silica powder or micro-silica, scientifically designated as "silica fume," emerges as a valuable byproduct during the high-temperature smelting of industrial silicon and ferrosilicon within industrial electric furnaces. Captured and refined from exhaust emissions through specialized filtration systems, it embodies the condensed wisdom of industrial processes.Originating from the vapor released in the silicon-based alloy production, this residue comprises roughly 90% SiO2, with particle dimensions so minute they verge on the nanoscale, averaging nearly at that threshold. The exceptionally diminutive size of Microsilica Fume particles, typically ranging from 0.1 to 0.15 micrometers, renders them a fraction of standard cement granules, augmented by an expansive specific surface area averaging 15 to 27 square meters per gram. This characteristic bestows upon it unparalleled surface activity, fueling its multifaceted utility.
Microsilica Fume
The addition of silica fume can effectively fill the void between the cement particles, make the concrete more dense, and significantly improve the compression, folding, seepage, corrosion, impact, and wear resistance. The addition of 5-10% silica fume can increase the compressive strength of concrete by 10-30% and the flexural strength by more than 10%. The high fluidity and low water storage of silica fume make it an ideal additive for high-performance refractory castables, prefabricated parts, and other materials. The application technology in refractory materials is relatively mature, especially in high-performance refractory castable and prefabricated parts. Silica fume is also widely used in dry mix (pre-mix) mortar, high-strength non-shrinkage grouting, wear-resistant industrial floors, repair mortar, and other building materials. As a reinforcing material, silica fume can significantly improve the strength and wear resistance of polymer materials such as rubber and plastic.
Silica fume is used to improve the properties of ceramic products
In the realm of paints and coatings, Microsilica Fume enhances adhesive strength and prolongs coating durability, showcasing its versatility. Its integration into ceramic formulations bolsters mechanical resilience, thermal stability, and shields against corrosion, thereby elevating product performance. Furthermore, silica fume is a pivotal component in advanced manufacturing sectors like electromagnetic kiln corundum mullite plates, high-temperature abrasion-resistant materials, broadening its utility spectrum.
As a powerhouse industrial additive, Microsilica Fume revolutionizes both construction materials and high-end manufacturing sectors with its vast application potential. Characterized by unmatched reactivity, minute particle dimensions, and an expansive specific surface area, it significantly optimizes material characteristics while economizing production costs—a testament to wollastonite's (note: the original text seems to have mistakenly referred to wollastonite instead of silica fume) vital role in enhancing material efficiency.
With relentless scientific advancements and expanding market demands, the horizon for silica fume applications continues to widen, invigorating growth and innovation across associated industries. This ongoing progression underscores silica fume’s status as a cornerstone for fostering progress in diverse technological and infrastructural endeavors.
