Iranian Company Produces Nanosilica in 3 Grades

“One of the strategic and widely used products made by our company is nanosilica or silicon dioxide nanopowder, which is considered as one of the most widely-used nanopowders in the world,” said Fakhari, the managing director of the company.

“The distinctive feature of nanosilica is that with slight changes in its structure and properties, diverse and specialized applications can be extracted from it,” he added.

“In the concrete industry, the use of nanosilica leads to the production of concrete with very high mechanical strength, and this material plays an important role as an effective additive in improving the performance of concrete in harsh environmental conditions, specially in urban and civil infrastructure,” Fakhari said.

“In the paint industry, nanosilica is also used as a rheological additive. This material helps to improve the quality and durability of industrial paints by improving the physical properties of the paint, including increasing resistance to moisture, scratches, and corrosion. Nanosilica has a special application in traffic paints that require high abrasion resistance and durability against harsh weather conditions,” he added.

Silicon dioxide nanoparticles, also known as silica nanoparticles or nanosilica, are the basis for a great deal of biomedical research due to their stability, low toxicity and ability to be functionalized with a range of molecules and polymers.

Nanosilica particles are divided into P-type and S-type according to their structure. The P-type particles are characterized by numerous nanopores, which have a pore rate of 0.61 ml/g and exhibit a higher ultraviolet reflectivity compared to the S-type; the latter also has a comparatively smaller surface area.

Nanosilica are the second most produced nanomaterial globally. Due to this, several research papers in recent decades have focused on the potential applications of nanosilica in multiple industries and their potential toxicity.
