Description and Specifications of Antimony Tin Oxide Nanoparticles
Antimony Tin Oxide (ATO) Nanoparticles are antimony-doped tin oxide nanoparticles with a spherical or faceted morphology and a high specific surface area. They combine high electrical conductivity, optical transparency, and infrared insulation, making them ideal transparent conductive nanoparticles for thermal-control applications. ATO nanoparticles are also available as aqueous dispersions in deionized water, as surface-treated or untreated powders.
They offer better dispersion characteristics, weather and wear resistance and chemical stability than many conventional conductive materials, making them suitable conductive nanoparticles for advanced coating and composite applications. These nanoparticles can be produced through several methods, including citric acid-assisted combustion synthesis using nitrate oxidants, sol-gel processing, co-precipitation, hydrothermal synthesis, and DC arc plasma jet techniques.

Applications of Antimony Tin Oxide Nanoparticles
As transparent conductive nanoparticles, ATO nanoparticles are used in optoelectronic devices, including LEDs, LCDs, ECDs, flat-panel displays, transparent electrodes, and solar cells. Their high electrical conductivity makes them suitable conductive nanoparticles for antistatic coatings, chemical fibers, polymer membranes, and other conductive applications.
Because of their heat resistance, these nanoparticles are used in hot mirrors, building glass, curtain walls, and glazing systems. They help reduce heat transfer. They are also used in automotive, railway, and aircraft glass. This helps reduce fogging and frost formation. They can block microwave radiation. For this reason, they are used for electromagnetic shielding in computer rooms, radar facilities, and other sensitive areas.
ATO nanoparticles are incorporated into coatings and composite materials to improve wear and scratch resistance, provide transparent UV protection, and enhance resistance to a wide range of organic and inorganic chemicals.
How to Use Antimony Tin Oxide Nanoparticles?
- Disperse the nanoparticles in a compatible solvent, resin, polymer, or coating formulation before application.
- Mechanical agitation or ultrasonic treatment may be used to improve particle distribution.
- Introduce the material slowly during preparation to reduce particle clustering.
- Coatings can be deposited by spray, dip, spin, or roll-coating methods, depending on the substrate and process requirements.
- Mix thoroughly before application to maintain uniform material properties throughout the formulation.
- Control coating thickness during application to obtain consistent film characteristics.
- Follow the specified drying, curing, or heat-treatment conditions for the selected process.
