Description

Silicon Dioxide (SiO₂) Nanopowder/Nanoparticles
Amorphous, Purity: 99.5+%, Size: 15–35 nm


Silicon Dioxide (SiO₂) Nanoparticles are ultra-fine, amorphous white powders with excellent chemical stability, high surface area, and high purity (99.5%+). With a particle size range of 15–35 nm and a specific surface area between 150–550 m²/g, these nanoparticles offer superior dispersibility and reactivity, making them ideal for a wide range of industrial, construction, and biomedical applications.

Applications:
Silicon Dioxide nanoparticles are widely used as high-performance fillers and additives in the production of plastics, rubber, ceramics, glass, adhesives, textiles, and paper. Their high surface area and ability to modify rheological and mechanical properties make them particularly effective as thickening agents, anti-caking agents, and flow-enhancers in powder processing.

In the construction industry, they are incorporated into cement, concrete, and composite materials to enhance compressive strength, durability, and resistance to cracking and shrinkage. In the biomedical field, amorphous SiO₂ nanoparticles are explored for use in drug delivery systems, diagnostics (theranostics), and bioimaging due to their biocompatibility and tunable surface functionalization.

Furthermore, they are employed in environmental protection technologies such as water purification systems, air filtration membranes, and as a carrier in controlled-release agricultural agents.
