Advancement in nanotechnology has led to the production of nanosized silica, SiO2, which has been widely used as filler in engineering composite. The silica particles extracted from natural resources contains metal impurities and not favorable for advanced scientific and industrial applications. Thus, focus is given to synthetic silica (colloidal silica, silica gels, pyrogenic silica, and precipitated silica), which is pure and produced mostly in amorphous powder forms compared to natural mineral silica (quartz, tridymite, cristobalite) which are in crystalline forms. Some of the widely used methods to synthesize silica nanoparticles are ion exchange and flame synthesis.
• ConstructionIn the construction sector, the capability to give a mechanical reinforcement to a cement based material is one of the most preferred properties of silica nanoparticles.• Polymer nanocompositesThe application of silica nanoparticles in the preparation of polymer nanocomposites is one of the prominent applications of them. These materials act as a filler or reinforcement in advanced composite materials with improved thermal, mechanical, physical and chemical properties.• Other applicationsDue to their high surface area and organized porous structure, mesoporous silica is an interesting material as stationary phases for high performance liquid chromatography (HPLC). In the field of biosensors, the mesoporous silica nanoparticles improve the sensitivity and response time of sensors due to their high porosity.
It is known as silica nanostructure powder with amorphous structure. Its purity is 93.43%.
The main advantage of nano silica is its high specific surface area in compared to micro silica which causes greater interactions in used environment.
