Silicon Oxide (SiO2) Nanopowder Main Feature
SiO₂ nanoparticles have a very high surface area to volume ratio. This characteristic is beneficial for applications requiring high reactivity or adsorption capacity, such as in catalysts, adsorbents, and drug delivery systems.Silicon oxide nanoparticles possess excellent optical transparency in the UV and visible light spectra, making them suitable for applications in optics, coatings, and paints where clarity and protection against UV degradation are desired.SiO₂ nanopowder demonstrates exceptional thermal stability, able to withstand high temperatures without significant degradation. This property is crucial for its use in high-temperature applications, including refractory materials, thermal insulation, and as a filler material to improve the thermal stability of composites.Silicon oxide is chemically inert, resistant to most acids and bases. This resistance makes it suitable for use in harsh chemical environments and as a protective coating to shield sensitive materials from corrosive substances.While SiO₂ in bulk form is brittle, its nanopowder can significantly improve the mechanical strength and durability of composites when used as a filler material. This enhancement is due to the nanopowder’s ability to disperse uniformly within a matrix and interact at the nanoscale with the host material.
